The fact that others have passed this challenge means they futzed with their code enough to pass the tests and didn't give it a second thought, but it seems counter to the instructions to me.

To be frank, it's rather bold to assume that your code is the only correct one and that the other 200+ coders who have passed this kata are wrong. And, while I generally prefer not to bring up rank as a heuristic justification, many of those who've passed are higher-rank coders on this platform while you're a 5kyu with less than 50 katas under your belt (most of which are white and yellow katas), a fact which would cast doubt on your claim.

This is not meant as a jab to diminish your competence as a coder. Oftentimes mistakes occur because some detail in the Description may not have been read or interpreted correctly, or a user makes an assumption about the rules that was never implicitly or explicitly stated (e.g. integers are mentioned and they assume only positive integers are involved).

It seems you've spent a considerable amount of effort working on this kata. Whether or not you pass it, hopefully you gain something positive from it (even if not the honor points).

Ok, marking issue as resolved then.

I think that's the problem. My final solution code is failing without any of the console logs appearing. It's failing in a fundamental way different from the test cases and I don't know why.

Is this issue valid? Looks like others are successfully completing this kata (albeit after some considerable effort).

I found the bad input by logging to the console input data to populate, move and constructor (NaN, boolean, string, out of bounds)

this issue is with the JavaScript translation?

looks like so, since it's the user's only language.

Just for clarification, this issue is with the JavaScript translation?

That's not cheating, that's just tests are badly written. Kata author/translator's fault.
