		const myEE = new EventEmitter();
		myEE.once('foo', () => console.log('a'));

		server.removeListener('connection', callback);

		`removeListener()` will remove, at most, one instance of a listener from the
		listener array. If any single listener has been added multiple times to the
		listener array for the specified `eventName`, then `removeListener()` must be
		called multiple times to remove each instance.
		
		Once an event is emitted, all listeners attached to it at the
		time of emitting are called in order. This implies that any`removeListener()` or `removeAllListeners()` calls _after_ emitting and _before_ the last listener finishes execution
		will not remove them from`emit()` in progress. Subsequent events behave as expected.
		
		```js
		import { EventEmitter } from 'node:events';
		class MyEmitter extends EventEmitter {}
		const myEmitter = new MyEmitter();
		
		const callbackA = () => {
		   console.log('A');
		   myEmitter.removeListener('event', callbackB);
		};
		
		const callbackB = () => {
		   console.log('B');
		};
		
		myEmitter.on('event', callbackA);
		
		myEmitter.on('event', callbackB);
		
		// callbackA removes listener callbackB but it will still be called.
		// Internal listener array at time of emit [callbackA, callbackB]
		myEmitter.emit('event');
		// Prints:
		//   A
		//   B
		
		// callbackB is now removed.
		// Internal listener array [callbackA]
		myEmitter.emit('event');
		// Prints:
		//   A
		```
		
		Because listeners are managed using an internal array, calling this will
		change the position indices of any listener registered _after_ the listener
		being removed. This will not impact the order in which listeners are called,
		but it means that any copies of the listener array as returned by
		the `emitter.listeners()` method will need to be recreated.
		
		When a single function has been added as a handler multiple times for a single
		event (as in the example below), `removeListener()` will remove the most
		recently added instance. In the example the `once('ping')`listener is removed:
		
		```js
		import { EventEmitter } from 'node:events';
		const ee = new EventEmitter();
		
		function pong() {
		   console.log('pong');
		}
		
		ee.on('ping', pong);
		ee.once('ping', pong);
		ee.removeListener('ping', pong);
		
		ee.emit('ping');
		ee.emit('ping');
		```
		
		Returns a reference to the `EventEmitter`, so that calls can be chained.
