WorkerGlobalScope.close()

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.
