JS Bin is a webapp specifically designed to help JavaScript and CSS folk test snippets of code, within some context, and debug the code collaboratively.

JS Bin allows you to edit and test JavaScript and HTML. Once you’re happy you can save, and send the URL to a peer for review or help. They can then make further changes saving anew if required.

The original idea spawned from helping developers debugging an Ajax issue. The original aim was to build it using Google’s app engine, but in the end, it was John Resig’s Learning app that inspired Remy Sharp to build the whole solution in JavaScript with liberal dashes of jQuery and a tiny bit of LAMP for the saving process.
