Option # 2

Use the date.format library:

var dateFormat = require('dateformat');
var now = new Date();
dateFormat(now, "dddd, mmmm dS, yyyy, h:MM:ss TT");

Using Moment.js

var moment = require('moment'); // require
moment().format();

For Node.js

var format = require('date-format');
format.asString(); // defaults to ISO8601 format and current date
format.asString(new Date()); // defaults to ISO8601 format
format.asString('hh:mm:ss.SSS', new Date());
