Is there a way to modify JavaScript code while debugging? Visual Studio has "Edit and Continue", and similar hot swapping of code can be done in Java and other languages. Can this be done with JavaScript, and if so, how?

Chrome, Safari, and some other WebKit-based browsers contain a feature in the Web Inspector known as Live Edit. If you go to the Scripts panel and are stopped on a breakpoint (or maybe even if not stopped on a breakpoint — I'm not sure), you can double click on a line and start editing that line. The changes you make will take effect on the script.
