The best part is the dependency on the function is_odd.

Can't even or can't odd? If only there was a way to find out =/

If I was a JS programmer, I'd just write a bash script to download it every week for fun.

300,000 every week... is this really a feature not built into Java Script?

(+x) % 2 == 0

If you forget for a second it's Javascript, the language will turn back and bite you.

This evaluates to NaN for some reason:

'10' % 0

Since JS doesn't really differentiate strings from numbers, except on the places it does, it makes sense to make sure you are working with numbers.

Oh right that. I guess I was visualizing a scenario where you already checked for it being a number, such as a Number.isInteger(x)

also, that suprises me a lot, you'd think this is one of the places where it treats stuff as numbers

the remainder operator should return a number or a NaN right? do we actually need the triple here?

Not really. But with JS it's better safe than sorry.

The GP's addition is unnecessary, but I fully support anyone that decides to do it.

what a wonderful and beautiful language. i’m so glad i asked

And so wonderfully similar to the way that symbol is used in other languages as well. Gosh darn it I love JavaScript

the is_even package does not provide much worth indeed because it simply negates is_odd and thereby all its benefit.

It's dependency is_odd on the other hand provides at least some additional checks (it also checks if the value is a valid integer below the max int value)

And while I would indeed see uses for such methods (especially with the other checks, no simple oneliners) in some cases, especially in testing: This is stuff you write yourself, throw it in a e.g. NumberUtils class and everything is fine. You do never depend on an external library for that. The benefit (not spending a few seconds to write it) does not outweigh any of the drawbacks that come with external libraries.

Damn bro I haven’t seen this meme format in over 20 years! Hopefully you don’t spend all that time debugging those proprietary functions ya goof

Make it faster and jankier with precalculated lookup tables!
