The close() method of the WorkerGlobalScope interface discards any tasks queued in the WorkerGlobalScope's event loop, effectively closing this particular scope.
Syntax
self.close();
Example
If you wanted to close your worker instance from inside the worker itself, you could 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.
