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.
