The `Client` interface represents the window or the worker (defined as client)
that is [controlled][1] by the Service Worker. This object provides a no-op
constructor. Callers should note that only `Client` objects created by the user
agent (see [`this.clients.getServiced()`][2]) will provide meaningful
The `id` of a `Client` identifies the specific client object from the list of
client objects serviced by the Service Worker. The `postMessage(message,
targetOrigin, transfer)` method of a `[Client][3]`, when called, causes a
`[MessageEvent][4]` to be dispatched at the client object.
