unreadable ninja code.
as always on codewars

Why wouldn't it work?

How did you get passed of input is [0,0]?

Im speechless

So I basically am an idiot ?

I like the way you just used if and else without bothering yourself with the condition where el could be 0. Since adding 0 won't change anything, I think that's kinda smart

Nice! I like it.

Coercion in this way is really useful sometimes!

This is slick!

Nice one

Thanks broneck 🤗
