Notification.dir

The dir read-only property of the Notification interface indicates the text direction of the notification, as specified in the dir option of the Notification() constructor.

A DOMString specifying the text direction. Possible values are:

• auto: adopts the browser's language setting behavior (the default.)
• ltr: left to right.
• rtl : right to left.

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?',
  dir: 'rtl'
}

var n = new Notification('Test notification',options);

console.log(n.dir) // should return 'rtl'
