I get what adtac said, but, "not use node for cli tools?" Come on, so if I only know JavaScript and I want to build a cli tool for personal use that can later open source, shouldn't do it because the language?

That's not the hacker mentality, you can write a cli tool with JavaScript, Python, Lua, etc., make it work and there's nothing wrong with it. If you want to go full deep into cli tooling, then you start to looking into other languages that can fit into your new requirements.
