chatEmitter.js

var EventEmitter = require('events');

// 1. Create a new EventEmitter object and assign it to a variable called 'chat'.

// 2. Create a function named 'logMessage' to log the given 'message' argument to the console using console.log().

// 3. Listen for the 'message' event on our new chat object. Remember to add a callback that accepts the message parameter.

// 4. Add another listener for the 'join' event to log the welcoming message, "Welcome, " + name + "!".

// 5. On the chat object, emit the 'join' event and pass in your name as a string.

// 6. Finally, Emit the 'message' event twice on the chat object passing in any messages.
