This is my attempt to build Conway's Game of life in a TDD fashion, following the guidelines in Corey Haines' "4 Rules of Simple Design" The model was fairly simple, and it's now embellished with html, css and a 'controller' js file that bring the game to life. Download the source code, bring up the GameOfLife.html file in a browser, follow the instructions, and watch it go!
To run the tests, npm install, then npm test
