Correction. Debugging JS in not easy. I have been working on a native application which has some HTML5 components in webviews. There is no easy way in XCode to debug JS in this kind of mixed application. In fact, it is a royal pain in the ass. You can run the JS in Chrome debugger or a web development IDE, but that can only work if all your functionality is in HTML5/JS and not a mix of Native and HTML5.
