Does that package exist because JavaScript lacks a modulus operator (I feel like I remember it having one), or because the operator does/doesn’t coerce things into numbers the way you’d expect? Or is it honestly just laziness?
The package is written in javascript and uses the modulus operator.
It's just laziness and a cargo-cult mentality around package granularity that's gotten way out of hand. There's no rational basis for it.

$ node
> 10 % 3

> 10 % -3

edit: I called this operation "remainder" ... but you don't exactly say "10 remainder 3" for this operation. I don't know what to call it, "divide-by-and-return-absolute-of-whats-left" is not very catchy
- JavaScript is consistent with Java, PHP.
- Older C may behave as either Python or JavaScript.
- Modern C behaves like JavaScript.
So basically Python is the outlier here.
