Apllied. Thanks for the suggestion.

Sidenote: are you on CW discord server? Is it possible for you to go there and poke at one of us? ("yellow mods", on discord) We might have a suggestion for you ;)

Perfect solve

Crazy!

Why use [] ? because we need to return an array after using ...?

Nice, 1 is truthy

despite its abysmal rating i liked this kata. I think the problem lies in the sample tests: they pass with the initial code, and it's a bit hard to figure out what's going on by reading them, making users confused. I would suggest replacing the current sample tests with this, which is hopefully more streamlined and to the point:

describe("Tests suite", function () {
  const { doesNotThrow } = require('chai').assert;
  const doTest = (func, message) => doesNotThrow(func, undefined, undefined, message);

  it("sample tests", function () {
    doTest(_ => newFunction(), 'Your function is not even a function!.\n');
    doTest(_ => new newFunction(), 'Your function is old.\n');
    doTest(_ => new new newFunction(), 'Your function is middle-aged.\n');
    doTest(_ => new new new newFunction(), 'Your function is quite new, but not quite enough.\n');
  });
});

Это дичайший бред. Рекурсия вам в помощь.
