Class EventDispatcher<EventKeyType, EventMessageType>

Handles notifying listeners of events.

EventKeyType is used to distinguish events (e.g. a ClickEvent vs a TouchEvent) while EventMessageType is the type of the data sent with an event (can be void).

Example

const dispatcher = new EventDispatcher<'event1'|'event2'|'event3', void>();
dispatcher.on('event1', () => {
  console.log('Event 1 triggered.');
});
dispatcher.dispatch('event1');
