jsfiddle.net - it can be used for HTML, CSS, JQuery of most versions, pure JavaScript and more stuff I'm not familiar with myself. –  Shadow Wizard Jun 14 '11 at 10:07

I think you might be looking for jsfiddle ? Thats popular around these parts....

It allows you to play around with HTML, CSS and javascript on the fly, and also includes several versions of libraries such as JQuery to have a play with too.

Apparently Google Chrome Inspector also lets you edit code on the fly. Although I've never had too much luck using it for that. (Press F12 in Chrome then switch the the Script Tab)

www.jsfiddle.net for testing and editing code on the fly

www.jsperf.com for benchmarking and compairing code on the fly

www.jslint.com might help you for debugging (paired with json lint for checking validating json)

oh, and you can also just type in the url bar if you want to check for a cookie or a variable and you are in a hurry (try typing javascript: alert(1); in the url bar of your browser).
