FCC Unbeatable Tic Tac Toe

Feedback request for Unbeatable tic tac toe.

You should be testing your game also. I played one game and before I could play the last move, the game ended. I was X.

Also, in traditional Tic Tac Toe games, X always goes first, so if I select O as a player, the computer should make the first move.

Thanks for the feedback. I’ll try to improve that.
