/**
 * Much of the Node.js core API is built around an idiomatic asynchronous
 * event-driven architecture in which certain kinds of objects (called "emitters")
 * emit named events that cause `Function` objects ("listeners") to be called.
 *
 * For instance: a `net.Server` object emits an event each time a peer
 * connects to it; a `fs.ReadStream` emits an event when the file is opened;
 * a `stream` emits an event whenever data is available to be read.
 *
 * All objects that emit events are instances of the `EventEmitter` class. These
 * objects expose an `eventEmitter.on()` function that allows one or more
 * functions to be attached to named events emitted by the object. Typically,
 * event names are camel-cased strings but any valid JavaScript property key
 * can be used.
 *
 * When the `EventEmitter` object emits an event, all of the functions attached
 * to that specific event are called _synchronously_. Any values returned by the
 * called listeners are _ignored_ and discarded.
 *
 * The following example shows a simple `EventEmitter` instance with a single
 * listener. The `eventEmitter.on()` method is used to register listeners, while
 * the `eventEmitter.emit()` method is used to trigger the event.
 *
 * ```js
 * import { EventEmitter } from 'node:events';
 *
 * class MyEmitter extends EventEmitter {}
 *
 * const myEmitter = new MyEmitter();
 * myEmitter.on('event', () => {
 *   console.log('an event occurred!');
 * });
 * myEmitter.emit('event');
 * ```
