What's even wilder is if you look at the code of that package, all it does is include the is-odd package and then return !is-odd. And the is-odd package isn't much better, it does some basic checks on the input and then returns n % 2 === 1.
I thought I was missing something. JS is one of my main languages and I always just write the is-odd function myself since it's like 10 characters. It boggles the mind that is-even has 176k weekly downloads
To be fair having a name can make things easier to read. I get that
i % 2 == 0is a common pattern and most programmers will quickly recognize what is happening. ButisEven(i)is just that much easier to grok and leaves that brainpower to work on something else.But I would never import a package for it. I would just create a local helper for something this trivial.
Exactly what I would do if I had to reuse it, especially now since I know that adding a package would actually add 2. It all just seems so...inefficient
Even if the code isn't reused adding names to sub-expressions can be very valuable. Often times I introduce new functions or variables even if they are only used once so that I can give them a descriptive name which helps the reader more quickly understand what is happening.
Yeah, I do that with pretty much every separate operation in c# since our solutions are pretty big. Most of my JS scripts are just done in ServiceNow which are separated and named appropriately.
Also there are 40-something packages depending on it, so I guess it gets pulled automatically when they are used.
If youre lazy/busy enough, doing basic checks on the input is enough boilerplate to package out.
I’ve always looked at stuff like that as much more along the lines of performance art than anything else.
