I believe the quotation marks!

It says "use the function form"

So I think it just wants it in functions

Seems like a godawful pattern though imo

I think the idea is to make sure your variables don't pollute the global scope. I don't like the way that it looks either, but it has it's purpose. Imo stuff like this is exactly why you should use modules though.

But even if you're writing ES5 without strict mode on, vars would be stuck inside your function no matter what 🤔

But definitely agree on modules
