My team recently upgraded our Node version from 0.10 to 4.0 for a big app we are working on. Lots of improvements came in the upgrade, but by far, my favorite is all of the ES6 features now available natively in Node.

Just to be clear, Node 4.0 does not exhaustively support ES6. It implements a lot of the biggest new features, all incorporated from the upstream V8 engine. Getting all of these features–especially without having to set up up a build process with Babel or another compiler–has been a huge win for our team. We’ve been able to write cleaner, better JavaScript, and we’ve been gradually refactoring our app to use the new ES6 features. Read more on Using ES6 in Node.js…
