That's because your IDE does not have all the tests that are run by the testing suite for this kata on Codewars.

You will have to rely on the tests here on site. If you wish you, can print the input and observe the expected output for any one test. Then you could add that test to what you're using off-site. Personally, I think it's easiest to just stay on Codewars to complete these tasks for this reason.

When i move my solution on the other IDE i see all goes well but here my code doesn't pass

it should be here

Merged

JavaScript should use chai assertions

done there, also adding random tests (fixing this issue)

Ok, thank you

Your comparison function is not a valid comparison function. Comparers used in sort have to conform to specific requirements, and yours does not.

Hi. Whats the problem with tests for this kata? I have the same output as it need, sorted well. I checked it in jsbin, codepen, in console i see the wright output. But only codewars shows me not sorted output. What s is wrong?
