method Domain.prototype.add
Usage in Deno
```typescript import { Domain } from "node:node__domain.d.ts"; ```
Domain.prototype.add(emitter: EventEmitter | Timer): void
Explicitly adds an emitter to the domain. If any event handlers called by
the emitter throw an error, or if the emitter emits an `'error'` event, it
will be routed to the domain's `'error'` event, just like with implicit
binding.
This also works with timers that are returned from `setInterval()` and `setTimeout()`. If their callback function throws, it will be caught by
the domain `'error'` handler.
If the Timer or `EventEmitter` was already bound to a domain, it is removed
from that one, and bound to this one instead.
