WorkerGlobalScope.location

The location read-only property of the WorkerGlobalScope interface returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.

A WorkerLocation object.

If you called the following in a document served at localhost:8000

console.log(location);

inside a worker (which would basically be the equivalent of self.console.log(self.location);, as these are being called on the worker scope, which can be referenced with WorkerGlobalScope.self), you will get a WorkerLocation object written to the console — something like the following:

WorkerLocation {hash: "", search: "", pathname: "/worker.js", port: "8000", hostname: "localhost"…}
  hash: ""
  host: "localhost:8000"
  hostname: "localhost"
  href: "http://localhost:8000/worker.js"
  origin: "http://localhost:8000"
  pathname: "/worker.js"
  port: "8000"
  protocol: "http:"
  search: ""
  __proto__: WorkerLocation

You could use this location object to return more information about the document's location, as you might do with a normal Location object.
