I've seen a couple posts in the top in the last 6 hours feed, and it seems like people are really up in arms about this functional programming stuff. Not really sure what it even is.

It looks like it's people writing bad programming or something? Like a lot of extra stuff that is not necessary?

EDIT: sorry everyone, I'm not a programmer and I don't know to much other than a little java and python. I guess I should have posted this in Explain Like I'm Five.

In addendum to the side effects, functions can certainly have side effects, as the global state is still accessible, but only those that don't are considered "pure".
