This is why I like the web. I like online tools on the web which can save you time, energy or money. Jsbin is definitely one of them. Sometimes I just need to try out or debugg little parts of javascript code and maybe ask a friend for help with that. All there is needed is to point my browser to jsbin website and start working. It has a very simple interface, just with three tabs, Javascript, HTML, Output. Just include the javascript library you prefer from the drop down menu and off you go. Maybe you want to send the code to someone else to ask for help, opinion, whatever, just hit the button share to public url and send that link to anyone. Combine this with the power of firebug and you got a very handy javascript online debugging tool.
