My code for Tic-Tac-Toe (beginner), compared to my mate that works at google's code.

Thought it would be interesting seeing someone beginner code, vs someone's professional code on the same project. After I sent him my code he replied with how he would have done it, as a comparison.

**My code:**

global winner
