yes, the tests in this kata are very bad. almost as bad as your ability to read the instructions

Good job, now try to solve it again with no temporary arrays :)

I'm glad u enjoyed it 😊

You can solve kata in different languages. That won't affect your honor or your overall rank, but that will increase the rank for those languages, yes. XFRXLP is talking about trying solutions of other users in the language you already solved (and so, to not try them in the trainer but to use the fork panel)

Some readings about rank/honor

No, but don't copy/paste the solutions in the trainer. Incase, if you want to analyse the solution, click on "Fork" and then "Run".

You might want ot read this again, it has been updated a couple of hours ago. In new kata, Test should not be used, as it was superseded by Mocha and Chai.

Latter can do the job, right?

If not, you can do: const Test = require("@codewars/test-compat");
(I've never created a kata, but I usually see Test. being used in Node < 10 versions)
