EventTarget — listener fires on dispatchEvent

📖 Usage Example

const et = new EventTarget()
et.addEventListener('ping', () => console.log('pong'))
et.dispatchEvent(new Event('ping'))  // → pong

addEventListener registers a listener; dispatchEvent fires the event.

EventTarget.addEventListener / dispatchEvent

When you dispatch an event on an EventTarget, any listeners registered for that event type are called synchronously.

Challenge: Verify that a listener registered with addEventListener fires when dispatchEvent is called.
