I’d like to use new features in my projects like ES modules.
This project lists all the available Node versions on Glitch: Please add Node.js v13.0 to Glitch.
No v13 available yet.
Lol it barely supports 12.
It is advisable to use latest LTS version in production-grade apps. Should do you choose new features over getting support? For me, no thanks, unless you want.
