There’s a bit more nuance as to why. It’s not fair to say that the average JS dev is reaching for a package like is-odd/is-even.

Years ago when npm was just getting started there was a lot of experimentation and land grabbing for packages. A few “prolific” developers were pushing these tiny utilities and then using them in their own projects which ended up being required as deps in other projects and then snowballed into is-odd being included in webpack at some point (I think I have that timeline roughly correct).

It’s still a crappy problem for sure but it’s not fair to paint most JS devs with a brush so broad.
