<h2 id="Syntax">Syntax</h2>

<pre class="syntaxbox">var <em>lang</em> = navigator.language
</pre>

<h3 id="Value">Value</h3>

<p>A {{domxref("DOMString")}}. <em><code>lang</code></em> stores a string representing the language version as defined in <a class="external" href="http://www.ietf.org/rfc/bcp/bcp47.txt">BCP 47</a>. Examples of valid language codes include "en", "en-US", "fr", "fr-FR", "es-ES", etc.</p>

<p>Note that in Safari on macOS and iOS prior to 10.2, the country code returned is lowercase: "en-us", "fr-fr" etc.</p>

<p>[1] Returns the browser UI language, not the value of the <code>Accept-Language</code> <a href="/en-US/docs/Web/HTTP/Headers">HTTP header</a>.</p>

<p>[2] Prior to Gecko 2.0 {{geckoRelease("2.0")}}, this property's value was also part of the user agent string, as reported by {{domxref("window.navigator.userAgent", "navigator.userAgent")}}.</p>

<p>[3] Starting in Gecko 5.0 {{geckoRelease("5.0")}}, this property's value is based on the value of the <code>Accept-Language</code> <a href="en-US/docs/Web/HTTP/Headers">HTTP header</a>.</p>
