 *
 * @example
 * ```typescript
 * const dispatcher = new EventDispatcher();
 *
 * function onEvent(event: DispatcherEvent) {
 *     console.log(event.type);
 * }
 *
 * dispatcher.addEventListener('testEvent', onEvent);
 * dispatcher.dispatchEvent({ type: 'testEvent' });
 * dispatcher.removeEventListener('testEvent', onEvent);
 * ```
