SharedWorker extension type
The SharedWorker
interface represents a specific kind of worker that
can be accessed from several browsing contexts, such as several windows,
iframes or even workers. They implement an interface different than
dedicated workers and have a different global scope,
SharedWorkerGlobalScope.
Note: If SharedWorker can be accessed from several browsing contexts, all those browsing contexts must share the exact same origin (same protocol, host and port).
