The onlanguagechange property of the WindowEventHandlers mixin is the EventHandler for processing languagechange events.

These events are received by the object implementing this interface, usually a Window, an HTMLBodyElement, or an HTMLIFrameElement. Such an event is sent by the browser to inform that the preferred languages list has been updated. The list is accessible via NavigatorLanguage.languages.

window.onlanguagechange = function(event) {
  console.log('languagechange event detected!');
};
