Thanks a lot! I didn't understand whats a problem, your comment helped me!

Thank u. I spent a lot of time solving this problem

Just a nice, simple method!

@nmoadev You should add it to the description too.

u jealous? lol

1 liners don't make you a better programmer.

Yes. Javascript allows you to treat strings as character arrays, so str[0] refers to the first character of str.

The only difference between accessing it like an array and using charAt (or any of the other string methods... slice, substr, or substring) is that if the index refers to a position outside the string's length, str[i] will result in the value undefined, while those other methods would return an empty string instead.

Is this how str[0] works here? for example: abc

"abc"
(reverse(bc) + "a")
(reverse(c) + "b") + "a")
("c" + "b" + "a")
"cba"

Nevermind. I see the kata has an error within the tests regarding, JS and CoffeeScript.

Works fine when submitting.

Why should that result in an infinite loop?

I'm having a hard time figuring out how this is working without resulting in an infinite loop

Trying C# Broken Greetings, very excited you guys are supporting it. Unfortunately all I am getting is Submission Timed Out :(

Mind Blown....

Good suggestion. I'll fix that up.
