1.4. Getting Started

This section gives you a brief overview of your development environment, from the browsers in which your application will run to the development tools, such as profilers and timelines, that you will use during development. Feel free to skim this section and use it as a reference as necessary.

1.4.1. Specifications

Three specifications are pertinent to this book:

• HTML5 Canvas

• Timing control for script-based animations

• HTML5 video and audio

For historical reasons, there are actually two Canvas specifications that are nearly identical. One of those specifications is maintained by the W3C and can be found at http://dev.w3.org/html5/spec; the other specification is maintained by the WHATWG and can be found at http://bit.ly/qXWjOl. Furthermore, whereas the Canvas context is included in the WHATWG’s specification, the WC3 has a separate specification for the context, at http://dev.w3.org/html5/2dcontext.
