JavaScript applications consist of statements with an appropriate syntax. A single statement may span multiple lines. Multiple statements may occur on a single line if each statement is separated by a semicolon. This isn't a keyword, but a group of keywords.

- -

Statements and declarations by category

- -

For an alphabetical listing see the sidebar on the left.

- -

Control flow

- -
-
{{jsxref("Statements/block", "Block")}}
-
A block statement is used to group zero or more statements. The block is delimited by a pair of curly brackets.
-
{{jsxref("Statements/break", "break")}}
-
Terminates the current loop, switch, or label statement and transfers program control to the statement following the terminated statement.
-
{{jsxref("Statements/continue", "continue")}}
-
Terminates execution of the statements in the current iteration of the current or labeled loop, and continues execution of the loop with the next iteration.
-
{{jsxref("Statements/Empty", "Empty")}}
-
An empty statement is used to provide no statement, although the JavaScript syntax would expect one.
-
{{jsxref("Statements/if...else", "if...else")}}
-
Executes a statement if a specified condition is true. If the condition is false, another statement can be executed.
-
{{jsxref("Statements/switch", "switch")}}
-
Evaluates an expression, matching the expression's value to a case clause, and executes statements associated with that case.
-
{{jsxref("Statements/throw", "throw")}}
-
Throws a user-defined exception.
-
{{jsxref("Statements/try...catch", "try...catch")}}
-
Marks a block of statements to try, and specifies a response, should an exception be thrown.
-
- -

Declarations

- -
-
{{jsxref("Statements/var", "var")}}
-
Declares a variable, optionally initializing it to a value.
-
{{jsxref("Statements/let", "let")}}
-
Declares a block scope local variable, optionally initializing it to a value.
-
{{jsxref("Statements/const", "const")}}
-
Declares a read-only named constant.
-
- -

Functions and classes

- -
-
{{jsxref("Statements/function", "function")}}
-
Declares a function with the specified parameters.
-
{{jsxref("Statements/function*", "function*")}}
-
Generators functions enable writing iterators more easily.
-
{{jsxref("Statements/return", "return")}}
-
Specifies the value to be returned by a function.
-
{{jsxref("Statements/class", "class")}}
-
Declares a class.
-
- -

Iterations

- -
-
{{jsxref("Statements/do...while", "do...while")}}
-
Creates a loop that executes a specified statement until the test condition evaluates to false. The condition is evaluated after executing the statement, resulting in the specified statement executing at least once.
-
{{jsxref("Statements/for", "for")}}
-
Creates a loop that consists of three optional expressions, enclosed in parentheses and separated by semicolons, followed by a statement executed in the loop.
-
{{deprecated_inline}} {{non-standard_inline()}} {{jsxref("Statements/for_each...in", "for each...in")}}
-
Iterates a specified variable over all values of object's properties. For each distinct property, a specified statement is executed.
-
{{jsxref("Statements/for...in", "for...in")}}
-
Iterates over the enumerable properties of an object, in arbitrary order. For each distinct property, statements can be executed.
-
{{jsxref("Statements/for...of", "for...of")}}
-
Iterates over iterable objects (including {{jsxref("Global_Objects/Array","arrays","","true")}}, array-like objects, iterators and generators), invoking a custom iteration hook with statements to be executed for the value of each distinct property.
-
{{jsxref("Statements/while", "while")}}
-
Creates a loop that executes a specified statement as long as the test condition evaluates to true. The condition is evaluated before executing the statement.
-
- -

Others

- -
-
{{jsxref("Statements/debugger", "debugger")}}
-
Invokes any available debugging functionality. If no debugging functionality is available, this statement has no effect.
-
{{jsxref("Statements/export", "export")}}
-
Used to export functions to make them available for imports in external modules, another scripts.
-
{{jsxref("Statements/import", "import")}}
-
Used to import functions exported from an external module, another script.
-
{{jsxref("Statements/label", "label")}}
-
Provides a statement with an identifier that you can refer to using a break or continue statement.
-
- -
-
{{deprecated_inline}} {{jsxref("Statements/with", "with")}}
-
Extends the scope chain for a statement.

ال return ينهي البيان تنفيذ الوظيفة ويحدد قيمة ليتم ارجاعها الى دالة الاستدعاء

- -
{{EmbedInteractiveExample("pages/js/statement-return.html")}}
- - - -

بناء الجملة

- -
return [expression];
- -
-
expression
-
التعبير المراد استرجاع قيمتة. اذا تم حذفه, فسيتم ارجاع undefined بدلاً من ذالك
-
- -

الوصف

- -

عند استخدام عبارة return في جسم الدالة,يتم ايقاف تنفيذ الوظيفة.اذا تم تحديد ذالك,يتم ارجاع قيمة معينة الى دالة الاستدعاء.على سبيل المثال,تعرض الدالة التالية مربع سعتها , x,حيث x هي رقم.

- -
function square(x) {
-   return x * x;
-}
-var demo = square(3);
-// demo will equal 9
-
- -

اذا تم حذف القيمة,يتم ارجاع undefined بدلاُ من ذالك

- -

تعطل عبارات الارجاع التالية تنفيذ الوظيفة

- -
return;
-return true;
-return false;
-return x;
-return x + y / 3;
-
- -

الادراج التلقائي للفاصلة المنقوطة (Semicolon)

- -

تتاثر عبارة الارجاع بادراج الفاصلة المنقوطة تلقائياُُ (ASI) .

- -

لا يُسمح بفاصل سطر بين الكلمة الاساسية return  و التعبير

- -
return
-a + b;
-
- -

is transformed by ASI into:

- -
return;
-a + b;
-
- -

The console will warn "unreachable code after return statement".

- -
Starting with Firefox 40, a warning is shown in the console if unreachable code is found after a return statement.
- -

To avoid this problem (to prevent ASI), you could use parentheses:

- -
return (
-  a + b
-);
-
- -

Examples

- -

Interrupt a function

- -

A function immediately stops at the point where return is called.

- -
function counter() {
-  for (var count = 1; ; count++) {  // infinite loop
-    console.log(count + 'A'); // until 5
-      if (count === 5) {
-        return;
-      }
-      console.log(count + 'B');  // until 4
-    }
-  console.log(count + 'C');  // never appears
-}
-
-counter();
-
-// Output:
-// 1A
-// 1B
-// 2A
-// 2B
-// 3A
-// 3B
-// 4A
-// 4B
-// 5A
-
- -

Returning a function

- -
function magic() {
-  return function calc(x) { return x * 42; };
-}
-
-var answer = magic();
-answer(1337); // 56154
