docs: Fix EventEmitter initialization example (nodejs#245)

anddj · ZYSzys · commit de6f9314da7f · 2019-04-21T12:06:36.000+08:00
## Description We should consider using `new` keyword to properly instantiate EventEmitter class object, otherwise we get an error (as per current docs example): ```js const eventEmitter = require('events').EventEmitter() eventEmitter.on('start', () => { console.log('started') }) ``` ends up with: ``` TypeError: Cannot read property 'on' of undefined ``` Whereas instantiating with `new`: ```js const EventEmitter = require('events') const eventEmitter = new EventEmitter() console.log(eventEmitter instanceof EventEmitter) // true eventEmitter.on('start', () => { console.log('started') }) eventEmitter.emit('start') ``` outputs: ``` true started ``` ## Related Issues Fixes #242

 You initialize that using
 
 ```js
-const eventEmitter = require('events').EventEmitter()
+const EventEmitter = require('events')
+const eventEmitter = new EventEmitter()
 ```
 
 This object exposes, among many others, the `on` and `emit` methods.
