<div>{{jsSidebar("Statements")}}</div>
<p>Break ifadesi içinde bulunduğu döngüyü , {{jsxref("Statements/switch", "switch")}}, or {{jsxref("Statements/label", "label")}} ifadelerini sonlandırır ve programın kontrolünü sonlandırılan ifadeyi ardından takip eden ifadeye geçirir.</p>
<div>{{EmbedInteractiveExample("pages/js/statement-break.html")}}</div>
<h2 id="Syntax">Syntax</h2>
<pre class="syntaxbox"><code>break [etiket];</code></pre>
<dl>
<dt><code>etiket</code></dt>
<dd>İsteğe bağlıdır.İfade etiketini tanımlamakta kullanılır. Eğer belirtilen ifade bir döngü ya da {{jsxref("Statements/switch", "switch")}} değilse, mutlaka kullanılması gerekir.</dd>
</dl>
<h2 id="Description">Description</h2>
<p>The <code>break</code> statement includes an optional label that allows the program to break out of a labeled statement. The <code>break</code> statement needs to be nested within the referenced label. The labeled statement can be any {{jsxref("Statements/block", "block")}} statement; it does not have to be preceded by a loop statement.</p>
<h2 id="Examples">Examples</h2>
<p>The following function has a <code>break</code> statement that terminates the {{jsxref("Statements/while", "while")}} loop when <code>i</code> is 3, and then returns the value 3 * <code>x</code>.</p>
<pre class="brush:js;highlight:[6];">function testBreak(x) {
var i = 0;
while (i < 6) {
if (i == 3) {
break;
}
i += 1;
}
return i * x;
}</pre>
<p>The following code uses <code>break</code> statements with labeled blocks. A <code>break</code> statement must be nested within any label it references. Notice that <code>inner_block</code> is nested within <code>outer_block</code>.</p>
<pre class="brush:js;highlight:[1,2,4];">outer_block: {
inner_block: {
console.log('1');
break outer_block; // breaks out of both inner_block and outer_block
console.log(':-('); // skipped
}
console.log('2'); // skipped
}
</pre>
<p>The following code also uses <code>break</code> statements with labeled blocks but generates a Syntax Error because its <code>break</code> statement is within <code>block_1</code> but references <code>block_2</code>. A <code>break</code> statement must always be nested within any label it references.</p>
<pre class="brush:js;highlight:[1,3,6];">block_1: {
console.log('1');
break block_2; // SyntaxError: label not found
}
block_2: {
console.log('2');
}
</pre>
