First, were going to need something to display the game. The HTML5 canvas element is essentially a sandbox of pixels that you can draw to dynamically. Were going to use a canvas to render the game, so we need to add it to our HTML page. Open default.html and replace Line 17 (the "Content goes here" line) with a canvas tag, so it looks like this:
Normally, youd specify width & height and add fallback content in case canvas isnt supported, but well set width/height later and we know canvas will be supported. However, this is just one of the many times you should consider coding practices in case you want to reuse some of your app code as a traditional web application but thats a story for another series of posts...
Making Things Easier with CreateJS
Well use PreloadJS to help load assets before to use in the game and EaselJS to make it easier to manage the game loop and the drawing of image assets.
