EventEmitter class lies in events module. It is ACCESSIBLY VIA following syntax:
//IMPORT events module
var events = require('events');
//create an eventEmitter object
var eventEmitter = new events.EventEmitter();
When an EventEmitter instance faces any error, it emits an 'error' event. When new listener is added, 'newListener' event is fired and when a listener is removed, 'removeListener' event is fired.
EventEmitter provides multiple properties LIKE on and emit. on property is used to bind a FUNCTION with the event and emit is used to fire an event.
