| |
| `self.onmessage` is the [event handler][1] that must be supported as attribute |
| by the `ServiceWorkerGlobalScope` object. `ServiceWorkerGlobalScope` objects |
| act as if they had an implicit `[MessagePort][2]` associated with them. This |
| port is part of a channel that is set up when the worker is created, but it is |
| not exposed. This object must never be garbage collected before the |
| `ServiceWorkerGlobalScope` object. |
| |
| All messages received by that port must immediately be retargeted at the |
| `ServiceWorkerGlobalScope` object. That is, an event named `message` using the |
| `[MessageEvent][3]` interface is dispatched on ServiceWorkerGlobalScope object. |
| The `event.source` of these `[MessageEvent][3]`s are instances of `[Client][4]`. |
