Why should it? April is in the 2nd quarter.

Don`t work with test case Expect(QuarterOf(4)).To(Equal(1))

good as shortest solution, but not obvious with magic numbers

that was because there were too much data to print to the console. Handled

There is something wrong with tests in JavaScript.
Trivial (and obviously wrong) code timed out. It shouldn't pass any test, but it must not time out.

function smaller(arr) {
  return [];
}

There's another kata that forbids use of string , this one's too late to change

NaN !== NaN. Default JavaScript behaviour.

Possibly you are under the impression that NaN === NaN.

I thought that it is about knowing decimal to binary converting algorithm, so i wrote my own converting function but... Now i see that i was wrong and this was just about learning toString() :)

Came here to look whether I didn't created a dulpicate kata, but just discovered I have created a kata which @alexeyten and @IVBakker wanted ^_^

It's ok now

Which solution exactly fails it? Those that I tested work fine with big numbers. But I'm not sure this kata was actually intended to test big numbers - that's rather a question to the author about his intentions, not an issue.

If your original issue is resolved, please mark this as resolved. Otherwise this kata will stay beta until you (or the author, who is probably now inactive) mark it as resolved.

Simple kata just need to be rated simple. Feel free to write another one linked to this one where you disable the trick.
