Not everyone likes Emacs Lisp, but I think there are two main arguments - one is speed, and the other is familiarity. Now that Emacs Lisp actually has native compilation, the speed issue is less of a problem, but it's a plain fact that a lot more people can do things with Javascript than Lisp. I think usually if you have an application you'd prefer to reuse a programming language rather than having a language specific to the application. I think that was the main motivation for the failed port to Scheme.
