BackgroundFetchEvent: BackgroundFetchEvent() constructor

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The BackgroundFetchEvent() constructor creates a new BackgroundFetchEvent object. This constructor is not typically used as the browser creates these objects itself and provides them to background fetch event callbacks.
