Every object in Node.js capable of emitting events is a member of the EventEmitter class. The http module is one such example.

All EventEmitter classes can use the eventEmitter.on() function to attach event listeners to the event. Then, as soon as such an event is caught, its listeners are called one by one synchronously.
