WorkerGlobalScope: reportError() method

Available in workers

The reportError() method of the WorkerGlobalScope interface may be used to report errors to the console or event handlers of global scopes, emulating an uncaught JavaScript exception.

This feature is primarily intended for custom event-dispatching or callback-manipulating libraries. Libraries can use this feature to catch errors in callback code and re-throw them to the top level handler. This ensures that an exception in one callback will not prevent others from being handled, while at the same time ensuring that stack trace information is still readily available for debugging at the top level.

See window.reportError() for more information.
