web api instance property
Notification: tag property
Secure context Available in workers
The tag read-only property of the
Notification interface signifies an identifying tag for the notification,
as specified in the tag option of the
Notification() constructor.
The idea of notification tags is that more than one notification can share the same tag, linking them together. One notification can then be programmatically replaced with another to avoid the users’ screen being filled up with a huge number of similar notifications.
Value
A string.
Examples
Our Using the Notifications API article has a good example of tag usage.
