So in conclusion... maybe checking whether a number is even in JS isn't as trivial as everyone thought, and projects reusing that code was a good thing?

Or are are all those extra checks unnecessary now that TypeScript exists and new functions like Number.isInteger have widespread browser support?

If so, the implementation of isEven isn't even right because it assumes anything that isn't an odd number is an even number.

No, the code posted in this thread clearly indicates it will raise an exception in such cases.

I think the assertion (sorry for the pun) is that JavaScript is a completely unholy creation and should be chucked off the edge of the disc.

I can’t imagine trying to get some of our fintech business logic in there without arming a nuclear foot gun or ten. I would never sleep again without medication.

TypeScript can't help at all, it vanishes before the code runs.
