-<p>JavaScript és orientat a objectes des del nucli, amb unes capacitats potents, flexibles {{Glossary("OOP")}}. Aquest article comença amb la introducció de la programació orientada a objectes, després es revisa el model d'objectes de Javascript, i finalment es mostren els conceptes de la programació orientada a objectes en JavaScript.</p>

-<p>Si no us sentiu segurs amb els conceptes de Javascript com ara variables, tipus, funcions, i àmbits podeu llegir sobre aquests temes en <a href="/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript">Una reintroducció a JavaScript</a>. També podeu consultar la <a href="/en-US/docs/Web/JavaScript/Guide">Guia de JavaScript</a>.</p>

-<h2 id="Object-oriented_programming" name="Object-oriented_programming">Programació orientada a Objectes</h2>
-
-<p>La programació orientada a Objectes és un paradigma de programació que usa l'abstracció per crear models basants en el món real. Fa servir diverseses tècniques de paradigmes previament establerts, inclosa la modularitat, poliformisme, i l'encapsulament. Avui, moltes llengües de programació (com Java, JavaScript, C#, C++, Python, PHP, Ruby i Objective-C) suporten la programació orientada a Objectes (POO).</p>
-
-<p>La programació orientada a Objectes es pot entendre com el disseny de software fent servir una col·lecció d'objectes que cooperen, al contrari de la visió tradicional en el qual un programa es vist com una col·lecció de funcions, o simplement com una llista d'instruccions per a un ordinador. En POO, cada objecte és capaç de rebre missatges, processar data, i enviar missatges a altres objectes. Cada objecte pot ser entès com una petita màquina independent amb un rol diferent o amb responsabilitat.</p>
-
-<p>La programació orientada a Objectes intenta promoure una major flexibilitat, mantenibilitat en programació, i és àmpliament popular en enginyeria de software a gran esala. En virtut de la seva forta èmfasi en modularitat, el codi orientat a objecte intenta ser més simple de desenvolupar i més facil d'entendre després, es presta a una anàlisi més directa, codificació, i comprensió de situacions complexes i procediments en comptes d'altres mètodes de programació menys modulars.<a href="#cite-1"><sup>1</sup></a></p>

-<h2 id="Programació_basada_en_prototipus">Programació basada en prototipus</h2>
-
-<p>Programació basat en prototipus és un estil de programació orientada a objectes que no fa ús de les classes. En el seu lloc, la reutilització del comportament (conegut com a herència en llenguatges basats en classes) es porta a terme a través d'un procés de decoració (o d'ampliació) on els objectes que ja existeixen serveixen com a prototipus. Aquest model també és conegut com a model sense classes, orientat a prototip, o programació basadad en instàncies.</p>
-
-<p>L'exemple original (i més canònic) d'un llenguatge basat en prototipus és el llenguatge de programació {{interwiki("wikipedia", "Self (programming language)", "Self")}} desenvolupat per David Ungar i Randall Smith. Tanmateix, l'estil de programació sense classes s'ha anat fent més i més popular, i ha sigut adoptat per llenguatges de programació com JavaScript, Cecil, NewtonScript, Io, MOO, REBOL, Kevo, Squeak (quan s'utilitza el marc Viewer per manipular components Morphic), i altres.<a href="#cite-1"><sup>1</sup></a></p>

-
-<h3 id="Namespace">Namespace</h3>
-
-<p>Un namespace és un contenidor el qual permet als desenvolupadors agrupar totes les funcionalitats sota un únic, nom d'aplicació específic. <strong>En JavaScript un namespace és només un altre objecte que conté mètodes, propietats, i objectes.</strong></p>
-
-<div class="note">
-<p><strong>Nota:</strong> Es important remarcar que en JavaScript, no hi ha diferèn<u>cia de nivell d'idioma entre els objectes regulars i els namespace</u>s. Això dista d'altres llenguatges orientats a objectes, i pot resultat confús als programadors nous en JavaScript.</p>
-</div>
-
-<p>La idea darrera la creació d'un namespace en JavaScript és simple: Un objecte global és creat i totes les variables, metòdes, i funcions es converteixen en propietats d'aquest objecte.<u> L'ús de namespaces també minimitza la possibilitat de conflictes de noms en l'aplicació, ja que cada objecte d'aplicació son propietats d'un objecte global d'aplicació definit</u>.</p>
-
-<p>Creem un objecte global anomenat MYAPP:</p>
-
-<pre class="brush: js">// global namespace
-var MYAPP = MYAPP || {};</pre>
-
-<p>En el codi de mostra superior, primer hem comprovat si MYAPP ja està definit (ja sigui en el mateix arxiu o en un altre arxiu). En cas de ser així, s'usa l'objecte global MYAPP existent, del contrari es crea un objecte buit anomenat MYAPP el qual encapsula el mètode, funcions, variables, i objectes.</p>
-
-<p>També podem crear sub-namespaces:</p>
-
-<pre class="brush: js">// sub namespace
-MYAPP.event = {};</pre>
-
-<p>Abaix es troba la sintaxi de codi per crear un namespace i afegir variables, funcions, i un mètode:</p>
-
-<pre class="brush: js">// Create container called MYAPP.commonMethod for common method and properties
-MYAPP.commonMethod = {
-  regExForName: "", // define regex for name validation
-  regExForPhone: "", // define regex for phone no validation
-  validateName: function(name){
-    // Do something with name, you can access regExForName variable
-    // using "this.regExForName"
-  },
-
-  validatePhoneNo: function(phoneNo){
-    // do something with phone number
-  }
-}
-
-// Object together with the method declarations
-MYAPP.event = {
-    addListener: function(el, type, fn) {
-    //  code stuff
-    },
-   removeListener: function(el, type, fn) {
-    // code stuff
-   },
-   getEvent: function(e) {
-   // code stuff
-   }
-
-   // Can add another method and properties
-}
-
-// Syntax for Using addListener method:
-MYAPP.event.addListener("yourel", "type", callback);</pre>
-
-<h3 id="Core_Objects" name="Core_Objects">Objectes estàndards integrats</h3>
-
-<p>JavaScript té alguns objectes inclosos en el seu nucli, per exemple, trobem objectes come Math, Object, Array, i String. L'exemple d'abaix ens mostra com fer servir l'objecte Math per aconseguir números aleatoris usant el seu mètode <code>random()</code>.</p>
-
-<pre class="brush: js">console.log(Math.random());
-</pre>
-
-<div class="note"><strong>Nota:</strong> Aquest i tots els exemples següents suposen que la funció anomenada {{domxref("console.log()")}} es defineix globalment. De fet, la funció <code>console.log()</code> no és part del llenguatge de JavaScript en si, però molts navegadors ho implementen per tal d'ajudar en la depuració.</div>
-
-<p>Vegeu <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects" title="en-US/docs/Web/JavaScript/Reference/Global_Objects">Referència de JavaScript: Objectes estàndards integrats</a> per una llista d'objectes cor en JavaScript.</p>
-
-<p>Cada objecte en JavaScript és una instància de l'objecte <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object"><code>Object</code></a> i per tant, n'hereda totes les seves propietats i mètodes.</p>
-
-<h3 id="Custom_Objects" name="Custom_Objects">Objectes personalitzats</h3>
-
-<h4 id="The_Class" name="The_Class">La classe</h4>
-
-<p>JavaScript és un llenguatge basat en prototipus que no conté<u> cap <code>class</code> statement, </u>el qual si que es pot trobar en C++ o Java. Això és confós a vegades per a programadors acostumats a llenguatges amb el <u><code>class</code> statement.</u> En el seu lloc, JavaScript fa servir funcions com a classes. Definir duna classe és tan fàcil com definir una funció. En l'exemple d'abaix definim una nova classe anomenada Person.</p>
-
-<pre class="brush: js">var Person = function () {};
-</pre>
-
-<h4 id="The_Object_.28Class_Instance.29" name="The_Object_.28Class_Instance.29">L'objecte (instància de classe)</h4>
-
-<p>Per crear una nova instància d'un objecte <code>obj</code> fem servir la declaració <code>new obj</code>, assignant el resultat (el qual és de tipus <code>obj</code>) a una variable per accedir-hi més tard. <span style="font-size: 14px; line-height: 1.5;">Una forma alternativa de crear una nova instància és fent servir {{jsxref("Object.create()")}}. Aquesta crearà una instància This will create an <u>uninititalized instance.</u></span></p>
-
-<p>En l'exemple d'adalt definim una classe anomenada <code>Person</code>. En l'exemple següent creem dues instàncies (<code>person1</code> i <code>person2</code>).</p>
-
-<pre class="brush: js">var person1 = new Person();
-var person2 = new Person();
-</pre>
-
-<div class="note"><strong>Nota:</strong> Siusplau vegeu {{jsxref("Object.create()")}} per un mètode instantacional nou, addiccional new, additional, instantiation mètode.</div>
-
-<h4 id="The_Constructor" name="The_Constructor">El constructor</h4>
-
-<p>El constructor és cridat en el moment de la instantiation (el moment en que la instància de l'objecte és creat). El constructor és ún mètode de la classe. En JavaScript la funció serveix com el constructor de l'objecte, therefore there is no need to explicitly define a constructor method. Every action declared in the class gets executed at the time of instantiation.</p>
-
-<p>El constructor es fa servir per establir les propietats de l'objecte o per cridar mè call methods to prepare the object for use. Per afegir mètodes de classes i les seves definicions es necessita una sintaxi diferent que s'explicarà més tard en aquest article.</p>
-
-<p>En l'exemple d'abaix, el constructor de la classe <code>Person</code> mostra un missatge quan és crea una instànca <code>Person</code>.</p>
-
-<pre class="brush: js">var Person = function () {
-  console.log('instance created');
-};
-
-var person1 = new Person();
-var person2 = new Person();
-</pre>
-
-<h4 id="The_Property_.28object_attribute.29" name="The_Property_.28object_attribute.29">La propietat (atribut de l'objecte)</h4>
-
-<p>Les propietats són variables contingudes en la classe; cada instància de l'objecte té aquestes propietats. Les propietats són asssignades en el constructor (funció) de la classe de forma que es creen en cada instància.</p>
-
-<p>Per treballar amb propietats de dins de la classe s'utilitza la paraula clau <code>this</code>, que fa referència a l'objecte actual. Accedir (llegir o escriure) a una propietat fora d'aquesta classe es fa mitjançant la sintaxi: <code>InstanceName.Property</code>; Aquesta és la mateixa sintaxi que es fa servir en C++, Java, i numeroses altres llengües. (Dins la classe, la sintaxi <code>this.Property</code> s'utilitza per obtindre o escriure el valor de les propietats.)</p>
-
-<p>En l'exemple següent definim la propietat <code>firstName</code> property per la classe <code>Person</code> i ho definim com a instanciació.</p>
-
-<pre class="brush: js">var Person = function (firstName) {
-  this.firstName = firstName;
-  console.log('Person instantiated');
-};
-
-var person1 = new Person('Alice');
-var person2 = new Person('Bob');
-
-// Show the firstName properties of the objects
-console.log('person1 is ' + person1.firstName); // logs "person1 is Alice"
-console.log('person2 is ' + person2.firstName); // logs "person2 is Bob"
-</pre>
-
-<h4 id="The_methods" name="The_methods">Els mètodes</h4>
-
-<p>Els mètodes segueixen la mateixa llògica que les propietats; la diferència es que són funcions i estan definides com a funcions. Cridar un mètode és similar a accedir a una propietat, però s'afegeix <code>()</code> al final the nom del mètode, possiblement amb arguments. Per definir un mètode, s'assigna una funció a una propietat amb nom de la propietat de la classe <code>prototype</code>; el nom que s'assigna a la funció és el mateix que el nom que té el mètode en l'objecte.</p>
-
-<p>En l'exemple següent definim i usem el mètode <code>sayHello()</code> per la classe <code>Person</code>.</p>
-
-<pre class="brush: js">var Person = function (firstName) {
-  this.firstName = firstName;
-};
-
-Person.prototype.sayHello = function() {
-  console.log("Hello, I'm " + this.firstName);
-};
-
-var person1 = new Person("Alice");
-var person2 = new Person("Bob");
-
-// call the Person sayHello method.
-person1.sayHello(); // logs "Hello, I'm Alice"
-person2.sayHello(); // logs "Hello, I'm Bob"
-</pre>
-
-<p>En JavaScript els mètodes són funcions normals dels objectes que són lligats a un objecte com una propietat, El que vol dir que poden ser invocats "fora del context". Vegeu el codi d'exemple següent:</p>
-
-<pre class="brush: js">var Person = function (firstName) {
-  this.firstName = firstName;
-};
-
-Person.prototype.sayHello = function() {
-  console.log("Hello, I'm " + this.firstName);
-};
-
-var person1 = new Person("Alice");
-var person2 = new Person("Bob");
-var helloFunction = person1.sayHello;
-
-// logs "Hello, I'm Alice"
-person1.sayHello();
-
-// logs "Hello, I'm Bob"
-person2.sayHello();
-
-// logs "Hello, I'm undefined" (or fails
-// with a TypeError in strict mode)
-helloFunction();
-
-// logs true
-console.log(helloFunction === person1.sayHello);
-
-// logs true
-console.log(helloFunction === Person.prototype.sayHello);
-
-// logs "Hello, I'm Alice"
-helloFunction.call(person1);</pre>
-
-<p>Com l'exemple mostra, totes les referències a la funció <code>sayHello</code> — les que existeixen a <code>person1</code>, a <code>Person.prototype</code>, a la variable <code>helloFunction</code>, etc. — fan referència a la <em>mateixa funció</em>. El valor de <code>this</code> durant una crida a la funció depen en com es crida. En el cas comú en que es crida la funció des d'una propietat de l'objecte — <code>person1.sayHello()</code> — <code>this</code> rep el valor de l'objecte d'on prové la propietat (<code>person1</code>), és per això que <code>person1.sayHello()</code> fa servir el nom "Alice" i <code>person2.sayHello()</code> fa servir el nom "Bob". Però si ho cridem d'altres maneres, <code>this</code> rebrà un valor diferent: Cridar-la des d'una variable — <code>helloFunction()</code> — <code>this</code> rep el valor de l'objecte global (<code>window</code>, en navegadors). Al no tenir la propietat <code>firstName aquest </code>objecte (probablement) , acabem amb el resultat "Hello, I'm undefined". (Això és en el mode no estricte; en el <a href="/en-US/docs/Web/JavaScript/Reference/Strict_mode" title="/en/docs/Web/JavaScript/Reference/Functions_and_function_scope/Strict_mode">mode estricte </a>seria diferent [un error], però per evitar confussions no entrarem aquí en detall.) O podem assignar explícitament el valor de <code>this</code> mitjançant <code>Function#call</code> (o <code>Function#apply</code>), com es mostra al final de l'exemple.</p>
-
-<div class="note"><strong>Nota:</strong> Vegeu més sobre <code>this</code> a <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/call" title="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/call">Function#call</a> i <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function/apply" title="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/apply">Function#apply</a></div>
-
-<h4 id="Inheritance" name="Inheritance">L'herència</h4>
-
-<p>L'herència és una manera de crear una classe com una versió especialitzada d'una o més classes (<em>JavaScript només suporta l'herència única</em>). La classe especialitzada és communment anomenada el <em>fill</em>, i l'altra classe es comunment anomenada el <em>pare</em>. En JavaScript això s'aconsegueix mitjançant l'assignació d'una instància de la classe pare a la classe fill, i després s'especialitza. En navegadors moderns també es pot usar <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create#Classical_inheritance_with_Object.create" title="/en-US/docs/JavaScript/Reference/Global_Objects/Object/create#Classical_inheritance_with_Object.create">Object.create</a> per implementar herències.</p>
-
-<div class="note">
-<p><strong>Nota:</strong> JavaScript does no detecta la classe fill <code>prototype.constructor</code> (vegeu <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/prototype">Object.prototype</a>), així que ho hem de declarar manualment.</p>
-</div>
-
-<p>En l'exemple d'abaix, definim la classe <code>Student</code> com una classe fill de <code>Person</code>. Després redefinim el mètode <code>sayHello()</code> i afegim el mètode <code>sayGoodBye()</code>.</p>
-
-<pre class="brush: js">// Define the Person constructor
-var Person = function(firstName) {
-  this.firstName = firstName;
-};
-
-// Add a couple of methods to Person.prototype
-Person.prototype.walk = function(){
-  console.log("I am walking!");
-};
-
-Person.prototype.sayHello = function(){
-  console.log("Hello, I'm " + this.firstName);
-};
-
-// Define the Student constructor
-function Student(firstName, subject) {
-  // Call the parent constructor, making sure (using Function#call)
-  // that "this" is set correctly during the call
-  Person.call(this, firstName);
-
-  // Initialize our Student-specific properties
-  this.subject = subject;
-};
-
-// Create a Student.prototype object that inherits from Person.prototype.
-// Note: A common error here is to use "new Person()" to create the
-// Student.prototype. That's incorrect for several reasons, not least
-// that we don't have anything to give Person for the "firstName"
-// argument. The correct place to call Person is above, where we call
-// it from Student.
-Student.prototype = Object.create(Person.prototype); // See note below
-
-// Set the "constructor" property to refer to Student
-Student.prototype.constructor = Student;
-
-// Replace the "sayHello" method
-Student.prototype.sayHello = function(){
-  console.log("Hello, I'm " + this.firstName + ". I'm studying "
-              + this.subject + ".");
-};
-
-// Add a "sayGoodBye" method
-Student.prototype.sayGoodBye = function(){
-  console.log("Goodbye!");
-};
-
-// Example usage:
-var student1 = new Student("Janet", "Applied Physics");
-student1.sayHello();   // "Hello, I'm Janet. I'm studying Applied Physics."
-student1.walk();       // "I am walking!"
-student1.sayGoodBye(); // "Goodbye!"
-
-// Check that instanceof works correctly
-console.log(student1 instanceof Person);  // true
-console.log(student1 instanceof Student); // true
-</pre>
-
-<p>Pel que fa a la línia <code>Student.prototype = Object.create(Person.prototype)</code>: En els motors de Javascript més antics sense <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create" title="Object.create"><code>Object.create</code></a>, es pot utilitzar tant un "polyfill" (també conegut com a  "falca", vegeu l'article enllaçat), o fer servir una funció que aconegueixi assolir el mateix resultat, tal com:</p>
-
-<pre class="brush: js">function createObject(proto) {
-    function ctor() { }
-    ctor.prototype = proto;
-    return new ctor();
-}
-
-// Usage:
-Student.prototype = createObject(Person.prototype);
-</pre>
-
-<div class="note"><strong>Nota:</strong> Vegeu <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/create" title="Object.create">Object.create</a> per més informació sobre el que fa, i una falca per a motors més vells.</div>
-
-<h4 id="Encapsulation" name="Encapsulation">L'encapsulació</h4>
-
-<p>En l'exemple anterior, <code>Student</code> no necessita saber com el mètode <code>Person</code> class's <code>walk()</code> és implementat, però tot i així pot fer-lo servir com a mètode; la classe <code>Student</code>no necessita definir explícitament aquest mètode a no ser que ho volguem canviar. D'això se'n diu <strong>encapsulació</strong>, per la qual cada classe empaqueta data i mètodes en una sola unitat.</p>
-
-<p>L'ocultació d'informació és una característica comuna en altres llenguatges sovint com a mètodes/propietats privats i protegits. Tot i que es podria simular alguna cosa com aquesta en JavaScript, no és un requeriment per fer programació orientada a objectes.<a href="#cite-2"><sup>2</sup></a></p>
-
-<h4 id="Abstraction" name="Abstraction">L'abstracció</h4>
-
-<p>L'abstracció és un mecanisme que permet modelar la part que ens ocupa del problema en el qual estem treballant. Això es pot aconseguir per mitjar de l'herència (especialització), o composició. JavaScript aconsegueix l'especialització per mitjà de l'herència, i la composició per mitjà de deixar a les instàncies de classes ser valors d'atributs d'altres objectes.</p>
-
-<p>La classe Function de JavaScript hereta de la classe Object (això demostra la especialització del model) i la propietat Function.prototype property és una instància d'Object (Això demostra composició).</p>
-

-<p>Tal i com tots els mètodes i propietats són definides dins la propietat Prototype, classes diferents poden definir mètodes amb el mateix nom; els mètodes estan en l'àmbit de la classe en la qual estan definits. Això només és cert quan les dues classes no tenen una relació pare-fill (quan un no hereta de l'altre en una cadena d'herència).</p>

-<p>Les tècniques presentades en aquesta article per implementar programació orientada a objectes no són les úniques que es poden fer servir en JavaScript, que és molt flexible en termes de com es pot realitzar la programació orientada a objectes.</p>
-
-<p>De la mateixa manera, les tècniques que s'han mostrat aquí no utilitzen cap <em>hack</em> del llenguatge, ni imiten cap implementació de teories d'objectes d'altres llenguatges.</p>
-
-<p>Hi ha altres tècniques que proporcionen programació orientada a objectes més avançada en JavaScript, però aquests estan fora de l'abast d'aquest article introductori.</p>

-<h2 id="Descripció">Descripció</h2>
-
-<p>A JavaScript, tots els objectes hereten de {{jsxref("Object")}}; tots els objectes hereten els mètodes i propietats de <code>Object.prototype</code>, tot i que es poden sobreescriure (excepte un <code>Object</code> amb prototipus <code>null</code>, és a dir, <code>Object.create(null)</code>). Per exemple, altres prototipus de constructors sobreescriuen la propietat <code>constructor</code> i ofereixen els seus propis mètodes {{jsxref("Object.prototype.toString()", "toString()")}}. Els canvis al prototipus <code>Object</code> es propaguen a tots els objectes a no ser que les propietats i mètodes que reben aquests canvis hagin sigut sobreescrites més avall a la cadena de prototipus.</p>

-<h2 id="Exemples">Exemples</h2>
-
-<p>Degut a que JavaScript no res semblant a subclasses d'objectes, la propietat <code>prototype</code> és una bona forma d'utilitzar algunes funcions que fan d'objectes com a "classe base". Per exemple:</p>
-
-<pre class="brush: js">var Person = function() {
-  this.canTalk = true;
-};
-
-Person.prototype.greet = function() {
-  if (this.canTalk) {
-    console.log('Hi, I am ' + this.name);
-  }
-};
-
-var Employee = function(name, title) {
-  Person.call(this);
-  this.name = name;
-  this.title = title;
-};
-
-Employee.prototype = Object.create(Person.prototype);
-Employee.prototype.constructor = Employee;
-
-Employee.prototype.greet = function() {
-  if (this.canTalk) {
-    console.log('Hi, I am ' + this.name + ', the ' + this.title);
-  }
-};
-
-var Customer = function(name) {
-  Person.call(this);
-  this.name = name;
-};
-
-Customer.prototype = Object.create(Person.prototype);
-Customer.prototype.constructor = Customer;
-
-var Mime = function(name) {

-  this.name = name;
-  this.canTalk = false;
-};
-
-Mime.prototype = Object.create(Person.prototype);
-Mime.prototype.constructor = Mime;
-
-var bob = new Employee('Bob', 'Builder');

Altres canvis a l'array (com ara canviar un valor o bé eliminar un element) poden afectar els resultats de l'operació si el mètode visita els elements que han canviat. Tot i que el comportament específic d'aquests mètodes en aquests casos està ben definit no es recomana recolzar-se en ell ja que pot confondre a altres programadors que llegeixin el vostre codi. En comptes de modificar l'array copieu-lo i modifiqueu la copia.</p>

-<h3 id="Generic_methods" name="Generic_methods">Mètodes genèrics</h3>
-
-<p>Molts dels mètodes de l'objecte Array de JavaScript estan dissenyats per a ser aplicats de manera genèrica a qualsevol objecte que tingui la propietat <code>length</code> i que disposin la seva informació en forma de noms de propietats numèrices (com ara <code>array[5]</code> per a accedir a l'element desat a la posició 5). Alguns mètodes, com ara {{jsxref("Array.join", "join")}}, només llegeixen la propietat <code>length</code> i les altes propietats numèriques. D'altres mètodes, com ara {{jsxref("Array.reverse", "reverse")}}, necessiten que tant les propietats numèriques com la propietat <code>length</code> siguin mutables; això implica que aquests mètodes no es poden fer servir sobre objectes com ara {{jsxref("String")}}, on la seva propietat <code>length</code> així com les propietats numèriques no es poden modificar.</p>

Pot convertir cadenes de caràcters representant sencers i nombres en coma flotant, així com els valors <code>true</code>, <code>false</code> i <code>null</code>. Quant a nombres sencers, tant la notació decimal com la hexadecimal (denotada amb el prefixe "0x") estàn suportades. Els nombres negatius també estàn suportats (tot i que no per a hexadecimals).

-<p><strong>Els operadors de bits</strong> tracten els seus operands com una seqüència de 32 bits (uns i zeros), en comptes de operar-los com a <a href="/ca/docs/Web/JavaScript/Reference/Global_Objects/Number">nombres</a> decimals, hexadecimals o octals. Per exemple, la representació binària del és nombre decimal nou (9) 1001. Els operadors de bits treballen amb aquesta representació binària però el resultat que retorna l'operació sempre és un nombre standard de JavaScript.</p>

-<h2 id="Enters_de_32_bits_amb_signe">Enters de 32 bits amb signe</h2>
-
-<p>Els operands de totes les operacions de bits es converteixen a enters amb signe de 32 bits utilitzant el format de complement a 2. Això vol dir que la versió negativa d'un nombre (per exemple 5 vs -5) és exactament la mateixa representació binària però amb els bits invertits (operació de bits NOT del nombre, també coneguda com a complement del nombre) més 1. Per exemple, seguidament es mostra la representació binària de 314:</p>
-
-<pre>00000000000000000000000100111010
-</pre>
-
-<p>I a continuació <code>~314</code>, és a dir, el complement de <code>314</code>:</p>
-
-<pre>11111111111111111111111011000101
-</pre>
-
-<p>Finalment es mostra <code>-314</code>, és a dir, el complement a dos de <code>314</code>:</p>
-
-<pre>11111111111111111111111011000110
-</pre>
-
-<p>El complement a dos garanteix que el bit de més a l'esquerra sempre serà un <code>0</code> quan el nombre és positiu i un <code>1</code> quan el nombre sigui negatiu. Aquest bit és doncs anomentat el <em>bit de signe</em> degut a això.</p>
-
-<p>El nombre <code>0</code> es representa com a l'enter composat íntegrament de zeros a tots els seus bits.</p>
-
-<pre>0 (base 10) = 00000000000000000000000000000000 (base 2)
-</pre>
-
-<p>El nombre <code>-1</code> és l'enter composats completament per 1s a tots els seus bits.</p>
-
-<pre>-1 (base 10) = 11111111111111111111111111111111 (base 2)
-</pre>
-
-<p>El nombre <code>-2147483648</code> (representació hexadecimal: <code>-0x80000000</code>) és l'enter composat per zeros a tots els seus bits a excepciò del bit de més a l'esquerra, que és un 1.</p>
-
-<pre>-2147483648 (base 10) = 10000000000000000000000000000000 (base 2)
-</pre>
-
-<p>El nombre <code>2147483647</code> (representació hexadecimal: <code>0x7fffffff</code>) és el sencer composat per 1 a tots els seus bits a excepció del de més a l'esquerra.</p>
-
-<pre>2147483647 (base 10) = 01111111111111111111111111111111 (base 2)
-</pre>
-
-<p>Els nombres <code>-2147483648</code> i <code>2147483647</code> són els enters més petit i més gran respectivament que poden ser representats mitjançant un nombre de 32 bits amb signe.</p>
-
-<h2 id="Operadors_lògics_de_bits">Operadors lògics de bits</h2>
-
-<p>Conceptualment els operadors lògics de bits funcionen de la següent forma:</p>
-
-<ul>
- <li>Es converteixen els operans a enters de 32 bits amb signe, expressats com una sèrie de bits (zeros i uns).</li>
- <li>Cada bit del primer operand s'emparella amb el corresponent bit del segon operand: el primer bit amb el primer bit, el segon amb el segon, etcètera.</li>
- <li>L'operador s'aplica per cada parella de bits, tot construint el resultat bit a bit.</li>
-</ul>
-
-<h3 id="(AND_binari)"><a name="Bitwise_AND">&amp; (AND binari)</a></h3>
-
-<p>Realitza l'operació AND a cada parella de bits. <code>a</code> AND <code>b</code> esdevindrà 1 només si ambdós <code>a</code> i <code>b</code> són 1. La taula de la veritat per a l'operació  AND és la següent:</p>

-
-<p>Els operadors binaris de desplaçament accepten dos operands: el primer és el valor que serà transformat a enter de 32 bits i al que se li aplicarà el desplaçament. El segon determina el nombre de posicions que es desplaçarà cada bit. La direcció en la que els bits es desplaçaran es determina per l'operador usat.</p>
-
-<p>Els operadors de desplaçament converteixen els seus operands a enters de 32 bits en ordre <em>big-endian</em> i retornen un valor amb el mateix tipus que l'operand de l'esquerra. L'operand de la dreta hauria de ser menor de 32, però de no ser així només s'utilitzen els primers 5 bits.</p>
-
-<h3 id="&lt;&lt;_(Desplaçament_a_l'esquerra)"><a name="Left_shift">&lt;&lt; (Desplaçament a l'esquerra)</a></h3>
-
-<p>Aquest operador desplaça el primer operand un nombre específic de bits cap a l'esquerra. Els bits de l'esquerra sobrants són descartats. Per a omplir les primeres posicions de la dreta s'utilitzen zeros.</p>
-
-<p>Exemple<code>: 9 &lt;&lt; 2</code> resulta en 36:</p>
-
-<pre>     9 (base 10): 00000000000000000000000000001001 (base 2)

-9 &lt;&lt; 2 (base 10): 00000000000000000000000000100100 (base 2) = 36 (base 10)

-
-<h3 id=">>_(Desplaçament_a_la_dreta_preservant_el_signe)"><a name="Right_shift">&gt;&gt; (Desplaçament a la dreta preservant el signe)</a></h3>
-
-<p>Aquest operador desplaça el primer operand un nombre específic de bits a la dreta. Els bits sobrants es descarten. Els bits de l'esquerra s'inicialitzen amb el valor inicial del primer bit de l'esquerra. Degut a que el bit de més a l'esquerra tindrà el mateix valor que el bit de més a l'esquerra abans de realitzar el desplaçament, el bit de signe no canvia. És degut a aquesta propietat que es diu que aquest operand preserva el signe.</p>
-
-<p>Per exemple, <code>9 &gt;&gt; 2</code> resulta en 2:</p>
-
-<pre>     9 (base 10): 00000000000000000000000000001001 (base 2)

-9 &gt;&gt; 2 (base 10): 00000000000000000000000000000010 (base 2) = 2 (base 10)
-</pre>
-
-<p>De la mateixa manera, <code>-9 &gt;&gt; 2</code> resulta en -3, ja que el signe es preserva:</p>
-
-<pre>     -9 (base 10): 11111111111111111111111111110111 (base 2)

-
-<p>Aquest operador desplaça el primer operand un nombre específic de bits cap a la dreta. Els bits sobrants degut al desplaçament són descartats. Els bits de l'esquerra són omplerts utilitzant zeros. Com que el bit de signe sempre acaba sent un zero el resultat sempre és no negatiu.</p>
-
-<p>Per a nombres no negatius, els operadors de desplaçament a la dreta preservant el signe i omplint amb zeros retornen el mateix resultat. Per exemple, <code>9 &gt;&gt;&gt; 2</code> resulta en 2, tal com <code>9 &gt;&gt; 2</code>:</p>
-
-<pre>      9 (base 10): 00000000000000000000000000001001 (base 2)

-</pre>
-
-<p>El resultat varia, però, per a nombres negatius. Per exemple, <code>-9 &gt;&gt;&gt; 2</code> resulta en 1073741821, el qual es diferent de <code>-9 &gt;&gt; 2</code> (que retorna -3):</p>
-
-<pre>      -9 (base 10): 11111111111111111111111111110111 (base 2)

-<h3 id="Exemple_Marques_i_màscares_de_bits">Exemple: Marques i màscares de bits</h3>
-
-<p>Els operadors lògics de bits s'empren tot sovint per a crear, manipular i llegir seqüències de <em>marques</em>, les quals realitzen uns funció similar a les variables booleanes. El seu avantatge davant les variables booleanes és que les seqüències de marques utilitzen molta menys memòria (per un factor de 32).</p>
-
-<p>The bitwise logical operators are often used to create, manipulate, and read sequences of <em>flags</em>, which are like binary variables. Variables could be used instead of these sequences, but binary flags take much less memory (by a factor of 32).</p>
-
-<p>Suposem 4 marques:</p>
-
-<ul>
- <li>Marca A: tenim un problema de formigues</li>
- <li>Marca B: tenim un ratpenat</li>
- <li>Marca C: tenim un gat</li>
- <li>Marca D: tenim un ànec</li>
-</ul>
-
-<p>Aquestes marques són representades per una seqüència de bits: DCBA. Quan una marca està activada, té un valor de 1. Quan una marca no està activa rep un valor de 0. Suposem que una variable anomenada <code>flags</code> (marques en anglès) té el valor binari 0101:</p>
-
-<pre class="brush: js">var flags = 5;   // 0101 en binari
-</pre>
-
-<p>Aquest valor indica:</p>
-
-<ul>
- <li>La marca A està activa, és a dir, és certa (tenim un problema de formigues)</li>
- <li>La marca B és falsa (no tenim un murisec)</li>
- <li>La marca C és certa (tenim un gat)</li>
- <li>La marca D és falsa (no tenim un ànec)</li>
-</ul>
-
-<p>Com que les operacions be bits utilitzen nombres de 32 bits, 0101 és en realitat 00000000000000000000000000000101, però els zeros a l'esquerra es poden obviar ja que no contenen informació útil.</p>
-
-<p>Una <em>màscara de bits</em> és una seqüència que pot manipular i/o llegir marques. És molt comú definir màscares "primitives" per a cada marca:</p>
-
-<pre class="brush: js">var FLAG_A = 1; // 0001
-var FLAG_B = 2; // 0010
-var FLAG_C = 4; // 0100
-var FLAG_D = 8; // 1000
-</pre>
-
-<p>Es fàcil crear noves màscares mitjançant operacions de bits lògiques sobre les màscares primitives. Per exemple, la màscara de bits 1011 es pot crear mitjançant operacions OR sobre FLAG_A, FLAG_B i FLAG_D:</p>
-
-<pre class="brush: js">var mask = FLAG_A | FLAG_B | FLAG_D; // 0001 | 0010 | 1000 =&gt; 1011
-</pre>
-
-<p>Els valors individuals d'una marca es poden obtindre mitjançant una operació AND de la seqüència de marques amb la màscara primitiva corresponent. La màscara de bits descarta els bits de les marques que no s'escauen. Per exemple, la màscara de bits 0100 es pot emprar per veure si la marca C està activa:</p>
-
-<pre class="brush: js">// si tenim un gat...
-if (flags &amp; FLAG_C) { // 0101 &amp; 0100 =&gt; 0100 =&gt; true
-   // ... fer coses
-}
-</pre>
-
-<p>Una màscara de bits amb múltiples marques activades funciona com un "or". Per exemple els següents dos blocs de codi són equivalents:</p>
-
-<pre class="brush: js">// si tenim un ratpenat o un gat...
-// (0101 &amp; 0010) || (0101 &amp; 0100) =&gt; 0000 || 0100 =&gt; true
-if ((flags &amp; FLAG_B) || (flags &amp; FLAG_C)) {
-   // ... fer coses
-}
-</pre>
-
-<pre class="brush: js">// si tenim un ratpenat o un gat...
-var mask = FLAG_B | FLAG_C; // 0010 | 0100 =&gt; 0110
-if (flags &amp; mask) { // 0101 &amp; 0110 =&gt; 0100 =&gt; true
-   // ... fer coses
-}
-</pre>
-
-<p>Les marques es poden activar mitjançant una operació OR amb la màscara, on cada bit amb el valor 1 activarà la marca corresponent si no està ja activada. Per exemple, la màscara de bits 1100 pot ser emprada per a activar les marques C i D:</p>
-
-<pre class="brush: js">// si, tenim un gat i un ànec
-var mask = FLAG_C | FLAG_D; // 0100 | 1000 =&gt; 1100
-flags |= mask;   // 0101 | 1100 =&gt; 1101
-</pre>
-
-<p>Les marques es poden desactivar mitjançant una operació AND amb una màscara de bits, on cada bit amb el valor de zero desactivarà la marca corresponent si no està ja desactivada. Aquestes màscares poden generar-se fàcilment mitjançant una operació NOT sobre la màscara primitiva adient. Per exemple, la màscara 1010 pot ser emprada per a desactivar les marques A i C:</p>
-
-<pre class="brush: js">// no, no tenim un problema amb formigues ni tenim un gat
-var mask = ~(FLAG_A | FLAG_C); // ~0101 =&gt; 1010
-flags &amp;= mask;   // 1101 &amp; 1010 =&gt; 1000
-</pre>
-
-<p>També es podría haver creat la màscara amb <code>~FLAG_A &amp; ~FLAG_C</code> (Llei de De Morgan):</p>
-
-<pre class="brush: js">// no, no tenim un problema amb formigues ni tenim un gat
-var mask = ~FLAG_A &amp; ~FLAG_C;
-flags &amp;= mask;   // 1101 &amp; 1010 =&gt; 1000
-</pre>
-
-<p>Es pot invertir una màscara (entenem per invertir activar-la si està desactivada i desactivar-la si està activada. És a dir, invertir el seu valor) mitjançant una operació XOR amb una màscara de bits, on cada bit amb el valor 1 invertirà el valor de la marca corresponent. Per exemple, la màscara de bits 0110 pot ser emprada per invertir les marques B i C:</p>
-
-<pre class="brush: js">// Si no teniem un ratpenat, ara en tenim un
-// i si en teniem un, adéu ratpenat
-// El mateix amb els gats
-var mask = FLAG_B | FLAG_C;
-flags = flags ^ mask;   // 1100 ^ 0110 =&gt; 1010
-</pre>
-
-<p>Finalment, les marques poden ser invertides mitjançant l'operador NOT:</p>
-
-<pre class="brush: js">// entrant a l'univers paral·lel
-flags = ~flags;    // ~1010 =&gt; 0101

-
-<p>Els operadors lògics s'utilitzen normalment amb valors <code><a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean">Boolean</a></code> (lògics). En cas de serh-hi presents, retornen un valor booleà. Tot i així, els operadors <code>&amp;&amp;</code> i <code>||</code> retornen el valor d'un dels operands especificats, així que si aquests operadors es fan servir amb valors no booleans, poden retornar un valor no booleà.</p>
-
-<h2 id="Descripció">Descripció</h2>
-
-<p>Els operadors lògics es descriuren en la taula següent:</p>
-
-<table class="fullwidth-table">
- <tbody>
-  <tr>
-   <th>Operador</th>
-   <th>Ús</th>
-   <th>Descripció</th>
-  </tr>
-  <tr>
-   <td>AND lògic (<code>&amp;&amp;</code>)</td>
-   <td><code><em>expr1</em> &amp;&amp; <em>expr2</em></code></td>
-   <td>Retorna <code>expr1 </code>si es pot convertir en false; sinó, retorna expr2. Així, quan es fa servir amb valors booleans, <code>&amp;&amp;</code> retorna true si ambdós operands són true; de ser el contrari, retorna false.</td>
-  </tr>
-  <tr>
-   <td>OR lògic(<code>||</code>)</td>
-   <td><code><em>expr1</em> || <em>expr2</em></code></td>
-   <td>Retorna <code>expr1</code> si es pot converir en true; de ser al contrari, retorna <code>expr2</code>. Així, quan s'usa amb valors Booleans, <code>||</code> retorna true si l'operand és true; si amdós són false, retorna false.</td>
-  </tr>
-  <tr>
-   <td>NOT lògic (<code>!</code>)</td>
-   <td><code>!<em>expr</em></code></td>
-   <td>Retorna false si el seu únic operand pot convertir-se a true; sinó, retorna true.</td>
-  </tr>
- </tbody>
-</table>
-
-<p>Exemples d'expressions que es poden converir a false son aquelles que avaluen <code>null</code>, <code>0</code>, la cadena buida (""), o <code>undefined</code>.</p>
-
-<p>Tot i que els operadors <code>&amp;&amp;</code> i <code>||</code> es poden fer servir amb operands que no siguin valors Booleans, poden ser considerats operadors Booleans ja que els valors que retornen sempre es poden convertir en valors Booleans.</p>
-
-<h3 id="Short-Circuit_Evaluation" name="Short-Circuit_Evaluation">Avaluació de tipus curtcircuit</h3>
-
-<p>Com a expressions lògiques que són, s'avaluen d'esquerra a dreta, they are tested for possible "short-circuit" evaluation fent servir les regles següents:</p>
-
-<ul>
- <li><code>false &amp;&amp; (<em>quelcom)</em></code> is short-circuit evaluated to false.</li>
- <li><code>true || (<em>quelcom)</em></code> is short-circuit evaluated to true.</li>
-</ul>
-
-<p>Les regles de la lògica garanteixen que aquestes avaluacions són sempre correctes. Fixeu-vos que la part <code><em>quelcom</em></code> d'adalt no s'avalua, així que els efectes secundaris d'això no tindràn efecte. Fixeu-vos també que la part de l'expressió de dalt anomenada <code><em>quelcom </em></code>és una expressió lògica simple (com s'indiquen amb els parèntesis).</p>
-
-<p>Per exemple, les dues funcions següents són equivalents.</p>
-
-<pre class="brush: js">function shortCircuitEvaluation() {
-  doSomething() || doSomethingElse()
-}
-
-function equivalentEvaluation() {
-  var flag = doSomething();
-  if (!flag) {
-    doSomethingElse();
-  }
-}
-</pre>
-
-<p>Tot i així, les següents expressions no són equivalents degut a la <a href="/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence">precendència dels operadors</a>, i remarca la importància de requerir que l'operador de la dreta sigui una sola expressió (agrupada, si s'escau, per parèntesi).</p>
-
-<pre class="brush: js">false &amp;&amp; true  || true      // returns true
-false &amp;&amp; (true || true)     // returns false</pre>
