JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

AI is half smart/half stupid by design. Originally I used the minimax algorithm, but that made for a pretty boring game, always ending in either a tie or a loss. So I made my own AI algorithm. The decision tree looks like this:
	1. Winning move available? ---> 
	2. Will lose next turn without blocking move? ---> 
	3. Choose a move at random
