HOW

EventEmitter is instantiated with new EventEmitter()
on binds an event listener and receives emitted data payload
multiple event listeners execute in order of registration
once binds a one-time event listener that executes only on the first emit
off removes an event listener so it is not invoked on subsequent emits
removeAllListeners(event) removes listeners for a specific event while preserving other events
removeAllListeners() without arguments clears all listeners for all events
on, once, off, and removeAllListeners return the EventEmitter instance for method chaining
