I used reduce. Look at my solution if you'd like to see an example.

How would you use reduce in this case?

Your comment made me curious, so I just tried the kata. Funny enough, my solution looks almost the same :D.

Of course there is a solution under 10 line, while mine is at least 20 :D Good job guys!

That was an original kata description, I really liked it!
But you forgot that we need to add the dressedInBlackLeather = true and the changesHair = true proeprties :)

Thank you! I appreciate it! // hun: Kösz!;)

I know it is not helpful, but I really liked this, even tough it is dead simple. The description was really fun!

Its fine if you want to make the kata harder, but

1. you should specify your behaviour in the spec, more than just the tests
2. you shouldn't put it in the 8 kyu section ( I think a simple return list[list.length-1]; would be more appropriate here

Lastly a personal opinion. There is no way in hell you would implement this function this way for a real world app.
That's why I find this Kata to be of little value.
