- 1. NodeJs
- 2. Node.js® is an open-source platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real- time applications that run across distributed devices. Current Version: v0.10.35 Excerpt - nodejs.org
- 3. Highlights Is able to run on every platform Microsoft is really backing the Node project Tons of modules (not just web) Run several instances, it’s single-threaded Great for heavy traffic and # of connections
- 4. Event Loop
- 5. Simple example var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello Worldn'); }).listen(1337, '127.0.0.1'); console.log('Server running at http://127.0.0.1:1337/');

- 7. Why Should I Care? Major companies are shifting over to it (Paypal, Walmart, Groupon, Medium) StackOverflow popularity: 66k+ posts Jobs (try searching Indeed or CareerBuilder)
- 8. Some practical uses Live reloading a web page locally Website builds (Grunt, Gulp) Making mobile apps (Titanium, Ionic) Meteor and CodeWars
