| <!-- |
| 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 |
| functionality. |
| |
| 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. |
