ReactJS Slide Puzzle

I put together a simple 3X3 slide puzzle as a first attempt at React.js. I was inspired after running through Brian Barnett's great Tic Tac React tutorial, and therefore mine shares much of the same code. I really recommend his post if you're interested in learning about React.

By default, React uses a XML-like syntax called JSX, which has already been compiled to plain JavaScript below. You can view the original, uncompiled source on GitHub.
