SharedWorkerGlobalScope

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The SharedWorkerGlobalScope object (the SharedWorker global scope) is accessible through the self keyword. Some additional global functions, namespaces objects, and constructors, not typically associated with the worker global scope, but available on it, are listed in the JavaScript Reference. See the complete list of functions available to workers.
