-<h2 id="Summary" name="Summary">Sommario</h2>
-<p>Il metodo <code><strong>Object.create()</strong></code> crea un nuovo oggetto a partire dall'oggetto prototipo e dalle proprietà specificati.</p>
-<h2 id="Syntax" name="Syntax">Sintassi</h2>
-<pre class="syntaxbox"><code>Object.create(<var>proto</var>[, <var>propertiesObject</var>])</code></pre>
-<h3 id="Parameters" name="Parameters">Parametri</h3>
-<dl>
- <dt>
- <code>proto</code></dt>
- <dd>
- L'oggetto che farà da prototipo per il nuovo oggetto creato.</dd>
- <dt>
- <code>propertiesObject</code></dt>

- Opzionale. Se specificato e non {{jsxref("Global_Objects/undefined", "undefined")}}, un oggetto le cui proprie proprietà enumerabili (ovvero, quelle proprietà definite esclusivamente su di sé e non quelle enumerabili presenti nella sua catena dei prototipi) specificano descrittori di proprietà da aggiungere all'oggetto appena creato, con i corrispondenti nomi di proprietà. Queste proprietà corrispondono al secondo argomento di {{jsxref("Object.defineProperties()")}}.</dd>

-<h3 id="Example:_Classical_inheritance_with_Object.create" name="Example:_Classical_inheritance_with_Object.create">Esempio: ereditarietà classica con <code>Object.create</code></h3>
-<p>Sotto, trovi un esempio di come implementare un'ereditarietà classica usando <code>Object.create</code>. Si tratta di un'ereditarietà singola, l'unica supportata da Javascript.</p>
-<pre class="brush: js">// Shape - superclass
-function Shape() {
- this.x = 0;
- this.y = 0;
-}
-
-// superclass method
-Shape.prototype.move = function(x, y) {
- this.x += x;
- this.y += y;
- console.info('Shape moved.');
-};
-
-// Rectangle - subclass
-function Rectangle() {
- Shape.call(this); // call super constructor.
-}
-
-// subclass extends superclass
-Rectangle.prototype = Object.create(Shape.prototype);
-Rectangle.prototype.constructor = Rectangle;
-
-var rect = new Rectangle();
-
-console.log("Is rect an instance of Rectangle? " + (rect instanceof Rectangle)); // true
-console.log("Is rect an instance of Shape<span style="font-size: 1rem;">? " + (rect instanceof Shape)); // true</span>
-
-rect.move(1, 1); // Outputs, 'Shape moved.'
-</pre>
-<p>Se desideri ereditare proprietà e metodi da oggetti multipli, puoi utilizzare dei mixins.</p>
-<pre class="brush: js">function MyClass() {
- SuperClass.call(this);
- OtherSuperClass.call(this);
-}
-
-MyClass.prototype = Object.create(SuperClass.prototype); // inherit
-mixin(MyClass.prototype, OtherSuperClass.prototype); // mixin
-
-MyClass.prototype.myMethod = function() {
- // do a thing
-};
-</pre>
-<p>La funzione <code>mixin</code> copia le funzioni dell'oggetto prototype della superclasse nell'oggetto prototype della sottoclasse; la funzione mixin deve essere implementata dall'utente. Un esempio di funzione simil mixin potrebbe essere <a href="http://api.jquery.com/jQuery.extend/">jQuery.extend</a>.</p>

-o = Object.create(Object.prototype, {
- // foo is a regular 'value property'
