SharedWorkerGlobalScope: close() method

The close() method of the SharedWorkerGlobalScope interface discards any tasks queued in the SharedWorkerGlobalScope's event loop, effectively closing this particular scope.

Syntax

js
close()

Parameters

None.

Return value

None (undefined).

Examples

If you want to close your worker instance from inside the worker itself, you can call the following:

js
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.
