The parameter passed into the ServiceWorkerGlobalScope.onfetch handler, FetchEvent represents a fetch action that is dispatched on the ServiceWorkerGlobalScope of a ServiceWorker. It contains information about the request and resulting response, and provides the FetchEvent.respondWith() method, which allows us to provide an arbitrary response back to the controlled page.
