How to modify javascript code on the fly in browser in debugging mode? [duplicate]

This question already has answers here: How can I edit javascript in my browser like I can use Firebug to edit CSS/HTML? (6 answers) 开发者_高级运维 Closed 5 months ago.

I want to use some IDE which allows me to change the javaScript code on the fly and run it in browser. I don't think I can do this in Firebug.

Which IDE/software should I use for JavaScript development?
