Nodejs is a minor JavaScript runtime, and the backward compatibility is not really an issue: There is breaking changes in the node standard library from time to time. That's the reason it was forked into io.js last year, and why they now use SemVer. The real compatibility issue is the web ! I built a small website for an association several years ago, it still works. What if Google Chrome decided to remove whatever JavaScript features I used at this time ?
