jsFiddle.net – simple, fast and very useful!

A tool I have found really useful for throwing together quick examples of HTML5/JavaScript is jsFiddle.net. It was built by Piotr Zalewa and designed by Oskar Krawczyk. It’s a browser based tool that has 4 panes allowing you to enter HTML, CSS, JavaScript and when you run your work it outputs the result in the fourth pane.

You can also select additional frameworks that you would like to include such as jQuery, Mootools, three.js.

Try it out :-)
