HOW

EventEmitter can be instantiated and exposes event listener and emission methods
on and emit register listener functions and synchronously invoke them with passed arguments
once registers a one-time listener that executes exactly once and is automatically removed
off removes a previously registered listener function for a specific event
removeAllListeners removes all listeners for a given event or all registered events
prependListener and prependOnceListener add listeners to the beginning of the invocation chain
EventEmitter.once static helper returns a promise resolving with event arguments when emitted
EventEmitter.on static helper returns an async iterable yielding event arguments until aborted
EventEmitter.forward lazily forwards events from a source emitter to a destination emitter
listenerCount and eventNames accurately reflect registered listeners on the emitter
