Same with me

I cannot be absolutely sure, but it's quite unlikely that your code returns a different result in VSCode and here (though, there may be minor differences of implementations, but this doesn't happen often). Your code works fine on several tests, but fails on some others, you should focus on it and try to find where your code is wrong:

Should return: ' Gap , gAp , gaP ': expected [ ' Gap ', ' gAp ', ' gaP ', ' gap ' ] to deeply equal [ ' Gap ', ' gAp ', ' gaP ' ]
