I have found the problem. I was changing the original array and it didn't like that. Make a duplicate array before you start sorting it.

I have tried serveral different solutions and I am having the same problem.

I am having the same issue as pshp and jesser. This is happening even when passing in a sorting function such as function sortNumber(a,b) {return a - b;}.

I am having the same issue. I don't know if I am reading it wrong.

I am sure I am doing it correctly, but some of the tests are expecting the wrong results.

For example:
Testing for Factom,MadeSafeCoin
✘ It should work for random inputs too - Expected: 'MadeSafeCoin', instead got: 'Factom'

My result is clearly correct and the expected result is wrong.
Am I missing something?
