jsFiddle: easy way to play with JS frameworks and share code snippets
jsFiddle is a nifty website which combines pastebin with a working dev environment. It's handy for fiddling about with code snippets, or for putting up code for a demo when asking a question.
You provide the HTML, JS, and any CSS, select a framework to be made available, then click the "Run" button to see your results. Then you can clear everything, or else save the code snippets and be given a URL to access them from.
Also nifty: you can simulate AJAX requests.
Overall, it takes out some of the pain of setting up a test case or quick discardable demo when sharing ideas with other people.
