Basically my intention is to create web application. I have to use js, ajax, jquery, html5, css etc... I would like to know if there is a web application development kit out there that helps me compile and debug my code? I am aware of "Aptana", but I am not sure if that is what I need. Can someone please eloberate what the choices available to me are. Total noob here to web development so I would like something that helps me learn as I go ahead developing!
