This is true in the language that you attempted it in (C++), but in most languages, this is an incredibly simple task. It may not have been the best idea to translate this to C++, but I think it's probably better to have the translation than not have it. In any case, this isn't really actionable as kata ranks cannot be changed. Even the C++ version of this kata I think is at most a 7kyu if you know the "easy" way to do it.

This isn't 8 kyu

I took the lack of information for the input as part of the challenge.
Use different console.logs to try to work out what the input is.

Lua translation!

very bad kata

Main problem I do not see what falls this test. I see only problem, it do not show me 's', if i return 's' I so not see what my function do. I return 's' and return all 'false'. I do it. but for it need very much time. decition have ony one string, but you do not see it, if you do not know basic funtion for it

You've hadcoded the answer for several input values, but not all, read the error message:

expected undefined to equal false

Your code isn't failing the test of -0, it is failing another one, but as your code is wrong, it is not a kata issue. Make some code that works at least without hardcoding every test and only then open an issue if you're sure there is a problem with the tests.

Something is wrong with the basic tests (all randoms passed)

I printed all of the ones with a result of false, but as per the description they shouldn't be true? (Added an extra condition to make the -0 into true and still fails..)

"s2324" false
"3 4" false
"3-4" false
"3 4 " false
"-0" false

All tests pass, one fails. Shit! What do I do? I'm upset! Very upset!

Not a kata issue.

Your solution fails for s = " ".
