6.4. Preloading Video in JavaScript

It is often necessary to preload a video before you do anything with it. This is especially true when using video with HTML5 Canvas because many times what you want to do goes beyond the simple act of playing the video.

We are going to leverage the DOM and JavaScript to create a preload architecture that can be reused and expanded upon. We are still not using Canvas, but this process will lead directly to it.
