This package in question has no dependencies and I can read the source code, can't do that with a binary.
Though I agree, but for other reasons, this tool is a bit silly in JS because you also need node, and it's basically just moving files around.
The issue is fragmenting tools between multiple package managers. That's a pain, and the source of my opposition to this concept here. Doubly so if they're language specific package managers (fine for development/in isolation, not for system wide user facing tools though).
Not really as npm and yarn are whole package managers that work in parallel to your distro's standard package manager. They pull various sources (that haven't been vetted by anyone except hopefully by the end programmer who told you to use npm install) from who knows where and install them either in your own home, or system-wide with -g like suggested here.
I would never use npm to install a system tool.
It looks like InderdeepBajwa, specifically, has tried to make a couple of projects in various languages: php, c++, go, python, javascript. So, the refrain 'write what you know' does not quite apply.
This is such a rude thing to say to someone providing free software. If you want to write tools in the language of your choice, then you're free to do so.
See how ridiculous it sounds now?
people are way more likely to be setup with npm than they are with cargo
Please don’t write command line tools in javascript. I’d never install npm, yarn… on my system just to try a tool out. CLI tools are perfect for compiled languages so you can distribute a binary.
