That could be one way to make it more interesting. Or maybe there could be a % chance to hit and a % critical chance, and they would have to estimate the average damage per attack. A kata similar to this one that was significantly harder had two fighters harming each other in turn, and required a knockout to be declared.

I think this is a little dangerous because I imagine there could be a situation with two people with the same name?
Still nice code!

For anyone reading- turns out not using "var" means you're declaring a global object. I have since refactored the code to include "var" because it bothered me.

Just realized that I forgot "var" was a part of Javascript while writing this code. Interesting that the language works in such a way that I got away with it.

I liked the problem but the directions said b->w instead of d->w which had me scratching my head for a bit at first.
