Very strange. Looking at your code, I believe that the codemirror mode gets stuck and hangs when it encounters )\ when the bracket is unmatched. I will try fix it as soon as possible (Note that this will apply to any LC kata, not just this one).

This kata is stuck on loading for me. Can you help with it?

This is so slow. Simple foreach loop is more than 10 times faster.
You have to do 2 iterations here. With loop you iterate only once.

bro make your kata a bit easier

I think you mean "wh4t"

Wow, this is great. Anyone mind explaining to me; why does adding a '+' make the strings which are next to each other included in one string as one element? And putting the 'aeiou' inside brackets tells Ruby you want to group each of the elements inside to their own element in the array?

In love with this one!

You can simplify this a bit with unsafeRegex from Data.String.Regex.Unsafe.

Very concise.

Wow, ive just check this solution and its actually wrong, Exception with "only one semicolon"!
