The lang read-only property of the Notification interface indicates the text direction of the notification, as specified in the lang option of the Notification() constructor.
The language itself is specified using a DOMString representing a BCP 47 language tag. See the Sitepoint ISO 2 letter language codes page for a simple reference.
var language = Notification.lang;
A DOMString specifying the language tag.
The following snippet fires a notification; a simple options object is created, then the notification is fired using the Notification() constructor.
var options = {
body: 'Do you like my body?',
lang: 'en-US'
}
var n = new Notification('Test notification',options);
