This is a confusing kata. There are no provided tests in JS and the provided comment and function header don't match the instructions. The submission tests pass in values that aren't numbers without that having been explained in the instructions. I was able to pass by hardcoding the solution, so there are insufficient random tests.

After fixing these issues, I'm still not sure the concept leaves much interest or originality. There are many other map/sort kata.

For the Javascript version of this Kata, the default solution and tests are for a completely different Kata entitled "twoOldestAges".
