I like this solution! :D like mine... but mine definetly uglier

Thanks for a such good Kata! I decided to make some Katas with guitar theme too. It's a nice new idea to make some Katas :)

Would be a good intermediate exercise in dealing with arrays and strings, but the addition of B# and E# was just plain annoying. Do you really need them, they're a special case that isn't mentioned in the description.

Fun ! Rated 6kyu

It will even throw an error if not an array. @_@

Fixed

In the description I mention this, in the 'Notes' section. First team alphabetically comes first.

JS random tests is using assert.equal, which is not what should be used (should be Test.assertEquals).

You have this test:

Test.assertEquals(canLeadersBeCaught([
  {
    name: 'Manchester City',
    points: 99,
    gamesPlayed: 37
  },
  {
    name: 'Chelsea',
    points: 99,
    gamesPlayed: 37
  },
]), 'The title race between Chelsea and Manchester City could be very close!')

Both teams have the same points and played the same amount of games. Then who should be the "leading" team (i.e the one comes first in the returned string)?

Resolved

Thanks!

Basically you generate random arguments, pass them to the user's solution and a solution of your own and compare the results.

How can I generate random tests?

Please add randomized tests.

Because this.

There are only 13 possible return values, so the kata is not interesting in the first place.

Not even random tests will help you there.
