io.js is a new runtime for your Node.js applications. It "Brings ES6 to the Node community" today. Also, you might have heard that io.js and NodeJs are going to merge. What you might not know is that the new version of node is a fork of io.js. So by knowing more about io.js, you will have a leg up as the next version of node is released. In this course, we will install io.js and see what we need to do to switch our existing applications over to using io.js. We will also do a quick check-in on the new possibilities that io.js supports in the form of EcmaScript 6. Finally we will deploy an io.js application to Heroku.
