I found an interesting thing - my sorting function is working perfectly in browser, but the result differs in codewars, that's why I can't solve the kata. And this this is not a first time when results differ. Would be very thankful for any advices or explanation.

@jsalinasf, I have faced exactly the same thing, and this is the main question - how to fixed something that is not visible. No errors, no timeout, nothing. Just half of tests is correct, another half is not and you can't discover what's wrong

You cant debug with console.log() because of large size of data. I can't see neither input data (games), it looks like "... 422534 more items ]", nor output "expected [ Array(978) ] to deeply equal [ Array(978) ]". Any thoughts how to solve this if you even don't know where the problem is hidden? As it was said above, all smaller tests are passed successfully.

I'm pretty new in js, so maybe i missed something, but i have a weird problem: when i make an attempt here i have about 70% correct answers, but if i try to run the same code with same s1 and s2 locally i have all correct answers, can somebody explain what's wrong?
