Nope. No idea what I was talking about. Looks good to me.

A horrible kata I enjoyed very much. So thank you... I think :)

That is AWESOME !!!

I assume the JavaScript array method 'flat' has been disabled? It doesn't seem to be working for me... I guess that makes sense, otherwise it would be a 'white' problem. But, even so, it would nice to be told so explicitly :)

Second attempt, after viewing better solutions in the community than my original solution.

Haha yes, I tend to be lazy (when tests permit). Making it efficient would considerably increace the difficulty.

How is this a 6kyu problem... I've encountered more difficult 8kyu problems than this.

"I'm looking around myself for one" -- haha, tell me that wasn't intentional :P

Coding 3min!! This took me nearly 3 days!!
Haha, but I got there in the end. A great problem!

I was litterally looking at every character in my answer to ensure my answer was formatted in exactly the same way as the expected test string. I kept failing. Then I read your comment, less than 20 seconds later I had passed all tests. Thank you :)

This is very cool, but I just checked the MDN and it is non-standard (i.e. won't work for every user) :/

JavaScripts Math.round() surely would give a more accurate answer than it's Math.floor() function. In the description instead of saying the result should be an integer, a better 'hint' would be "round down to the nearest integer" or "return the largest integer smaller than the actual value".
