The close() method of the DedicatedWorkerGlobalScope interface discards any tasks queued in the DedicatedWorkerGlobalScope's event loop, effectively closing this particular scope.
self.close();
If you want to close your worker instance from inside the worker itself, you can call the following:
close();
close() and self.close() are effectively equivalent — both represent close() being called from inside the worker's inner scope.
Note: There is also a way to stop the worker from the main thread: the Worker.terminate method.
