HTML5 Playground is built with simplicity in mind, and it's social from the start. It's being released as a beta Intel AppUp developer tool, and we will be rapidly adding features in the coming weeks. HTML5* Playground works in any HTML5* supported browser.
You can study working program code created by others, especially those that are leading in a particular technology. If you’re just starting to get your feet wet in HTML5, the HTML5 Playground Beta from Intel can help you to get to grips with the basics quickly.
This environment runs in your web browser enabling you to code and view code RAPIDLY.
To try all this good stuff, head on over to the HTML5 Playground.
