JS Bin
JS Bin is a tool for experimenting with web languages. In particular HTML, CSS and JavaScript, but JS Bin also supports other languages too (like Markdown, Jade and Sass). JS Bin is ultimately a code sharing site. Along with the code, the complete output of the code is also shared with other developers, colleagues and/or students. As you type into one of the editor “panels”, you and anyone watching your bin will see the output being generated in real-time in the output panel. There’s many features tucked away inside JS Bin, but our design principle is that everyone gets a cursor. So when you arrive for the first time, you’ll be greeted with an initial start HTML page and very little else (though you can customise your default code). If you register (which is free and simple), your profile will remember which bins you created, but also give you a shortcut URL that always takes you to the last bin you worked on.
