navigatorLanguage

NavigatorLanguage contains methods and properties related to the language of the navigator.

There is no object of type NavigatorLanguage, but other interfaces, like Navigator or WorkerNavigator, implement it.

The NavigatorLanguage interface doesn't inherit any property.

NavigatorLanguage.language Read only: Returns a DOMString representing the preferred language of the user, usually the language of the browser UI. The null value is returned when this is unknown.
NavigatorLanguage.languages Read only: Returns an array of DOMString representing the languages known to the user, by order of preference.

The NavigatorLanguage interface neither implements, nor inherit any method.
