unregister method
The unregister()
method of the
ServiceWorkerRegistration interface unregisters the service worker
registration and returns a Promise
. The promise will resolve to
false
if no registration was found, otherwise it resolves to
true
irrespective of whether unregistration happened or not (it may not
unregister if someone else just called ServiceWorkerContainer.register
with the same scope.) The service worker will finish any ongoing
operations before it is
unregistered.
Implementation
external JSPromise<JSBoolean> unregister();
