method EventEmitter.removeAllListeners
Usage in Deno
```typescript import { type EventEmitter } from "node:node__events.d.ts"; ```
EventEmitter.removeAllListeners(eventName?: Key<unknown, T>): this
Removes all listeners, or those of the specified `eventName`.
It is bad practice to remove listeners added elsewhere in the code,
particularly when the `EventEmitter` instance was created by some other
component or module (e.g. sockets or file streams).
Returns a reference to the `EventEmitter`, so that calls can be chained.
optional
eventName: Key<unknown, T>
