HOW

emitter.on registers an event listener and returns the emitter instance for chaining
emitter.on triggers the listener synchronously with all passed arguments when the event is emitted
emitter.on preserves the EventEmitter instance as this context within listener functions
emitter.on emits a newListener event before adding the listener to the emitter
emitter.on appends listeners in registration order and supports multiple listeners for the same event
EventEmitter.on static helper returns an async iterable yielding argument arrays for emitted events
EventEmitter.on queues emitted events until consumed by next
EventEmitter.on respects AbortSignal and rejects with OPERATION_ABORTED when aborted
EventEmitter.on cleans up its internal listeners when return is called on the iterator
EventEmitter.on rejects iterator promises when the emitter emits an error event
