Updating the message.js file

The first thing we're going to do is tweak our message.js file. Currently inside message.js, we generate timestamps using new Date().getTime.

var moment = require('moment');var generateMessage = (from, text) => {  return {    from,    text,    createAt: new Date().getTime()  };};
