The vibrate read-only property of the {{domxref("Notification")}}
interface specifies a vibration pattern
for the device's vibration hardware to emit when the notification fires. This is
specified in the vibrate option of the
{{domxref("Notification.Notification","Notification()")}} constructor.
A vibration pattern, as specified in the Vibration API spec.
The following snippet is intended to create a notification that also triggers a device
vibration; a simple options object is created, and then the notification is
fired using the Notification() constructor.
const options = {
body: "Your code submission has received 3 new review comments.",
vibrate: [200, 100, 200],
};
const n = new Notification("New review activity", options);
console.log(n.vibrate); // [200, 100, 200]
