Event Listeners are similar to call back functions but are associated with some event. For example when a server listens to http request on a given port a event will be generated and to specify http server has received and will invoke corresponding event listener. Basically, Event listener’s are also call backs for a corresponding event.
Node.js has built in event’s and built in event listeners. Node.js also provides functionality to create Custom events and Custom Event listeners.
