Thank you for that information.

No offense, but whoever thought this Kata up, I'd punch in the face, lol.

Sorry. I have trouble with double negatives (they derail my thought train instantly), and this Kata had tha audacity to pose not only triple negative logic, but then used poor semantics for the function naming (which just caused me to do another double take). lol.

OK, maybe not punch in the face, but you're buying first rounds. At the very least, you get a vigorous shaking of the fist at you. Akin to old ladies who want kids to get off their lawn.

LOL! After WRACKING my brain inside and out on why my solution was not working (it had passed 12+ tests I created in JSFiddle) I finally relented and Unlocked the Kata ONLY to find that the first, best solution was LETTER FOR LETTER the exact same solution I had. I'm new to Code Wars, but this counts the 3rd Kata where it refused my answer as being correct, and it wasn't. I'm really hoping that this isn't a trend on Code Wars. It's a great site for what it does, but it's debilatating to spend so much time on a problem and be told you're wrong only to find out you're FLAWLESSLY correct, and the engine/tests just failed to interpret your code properly.
