Installing node uses some 60MB (according to zypper on my current desktop). I'd rather have something small and possibly that consists of a single executable.
As a bonus, both support the vast and extensive NPM package repository
That's not necessarily a feature :) Package repos are great if you are a developer (I am one) working primarily with that language, but are frustrating if you just want to run things.
nim is great, but it is >200mb (plus AFAIK it is compiled... does it also have an interpreter?)
