WorkerNavigator: language property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.

Note: This feature is only available in Web Workers.

The WorkerNavigator.language read-only property returns a string representing the preferred language of the user, usually the language of the browser UI.

Value

A string representing the language version as a BCP 47 language tag, for example en, en-US, fr, fr-FR, es-ES, etc.

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

Examples

You can run this insert a web worker:

js
if (/^en\b/.test(navigator.language)) {
  doLangSelect(window.navigator.language);
}
