yeah this kata needs random tests

I usually manage 4kyu challenges in 30 mins or less, but this took me 6h40mins! I'm not inexperienced in code golfing.
It was an amazing challenge and I enjoyed every minute, even if I slowly lost my sanity.

I think it should be ranked 2 or 3 kyu

comp and lengthSupUK are terrible function names. I got stuck for 10 minutes thinking that comp was about calculating the nth number in u. Please change them to something more intuitive

you should test for the variable to be a regex, otherwise one could just use an object with a "test" method

if the tests result negative, you'll be printed a string similar to "isGreaterThan(-1, -4) should be true, because -4 > -1", and sometimes the numbers are the wrong way around

as a new test?

woops, forgot to remove the console.lo

this just makes sure that the number is divisible by 4, not that it's a power of 4

and of course 30! is too big of a number to be processed completely by js.

what?

Input: yaph
Output: Nice try, hacker :)

what??
