I have nothing against Emacs either, and I didn't say that there was anything wrong with its navigation. What I said was the assertion that Emacs and Vim have the best realtime analysis is just wrong - most Emacs modes have none at all. If you're interested in the implementation of this sort of functionality in Emacs, Steve Yegge's article on implementing JS2 mode is really interesting: http://steve-yegge.blogspot.co.nz/2008/03/js2-mode-new-javascript-mode-for-emacs.html http://steve-yegge.blogspot.co.nz/2008/03/js2-mode-new-javas.... He says at the end that IntelliJ's JavaScript support is just better, and it's very clear from the article how difficult it is to retrofit this sort of functionality into something that isn't built from the start to support it. But you're right that the tone of my comment wasn't great, and in general getting involved in these discussions is just a bad idea. Every so often I see a comment that makes it difficult to resist, but I always regret it.
