Is this deep-true method recommended to ensure that both score types === 'number' instead of 'string'?

How does it work?

Because when I wrote the kata, I felt that encouraging people to look at the documentation and write their own tests was appropriate for the level.

Basic Test Case:

describe("Example Tests", function () {
  it("Example Test Case", function () {
    Test.assertEquals(add(1, 1), 2, "optional message");
  });
});

Why there are no sample tests for JavaScript?

Recommend use === instead of ==.

Hi,

• Unfortunately, that's too much of a fuplicate. We alraedy have a lot of kata about vowels and changing case.
• no random tests

If you're interested in authoring kata, you should dive into the docs (especially the part about original ideas)

You should unpublish it, it has very little chances to get approved (dupliccate/not original enough).

Cheers
