ES6 support in Node.js?

Question

JavaScript

Hello!
I'm learning JavaScript and I want to try writing some stuff with EsmaScript 6. Should I use ES6 in Node.js already now? Are all ES6 features already supported and more or less stable? As I understand it, you still need to use the --harmony flag, but everything that I googled is somehow confused.
And yet, it seems like they wrote more than a month ago that the team from io.js should join node.js, but I watch new versions of io.js all come out and come out, somehow strange.

Answer 1

Options in order of the number of implemented features:
- translation to es5 with babel.js
- io.js
- what is in the node

Answer 2

What's stopping you from using Babel?
