Note: This property is not currently supported in any browser.
The sticky read-only property of the Notification interface specifies whether the notification should be 'sticky' or not. When we say a notification is sticky, it means that notification is not easily clearable by the user. This is specified in the sticky option of the Notification() constructor.
Syntax
var sticky = Notification.sticky;
Value
A Boolean. false is the default; true makes the notification 'sticky'.
Examples
The following snippet is intended to create a 'sticky' notification; a simple options object is created, then the notification is fired using the Notification() constructor.
var options = {
  body: 'Do you like my body?',
  sticky: true
}
var n = new Notification('Test notification',options);
n.sticky // should return true
