What version of Node are the functions using? I've been battling some errors that I had no indication about, I think it's because I was using arrow functions. Maybe we need some better syntax checking for the function editor, or some kind of indication

Internally they use webstask.io

Thanks!

The editor used is CodeMirror for React.js, that needs a definition (mode) for syntax highlighting. I can't figure out which mode they are using, but there doesn't seem to be one that exactly fits a specific node version though...
