Javascript is simpler - but more importantly, much more popular than Objective-C. It's also garbage collected, a feature that Objective-C may also have these days, but not when I last used it a couple of years ago.
Javascript's also a hell of a lot more popular than ruby, haskel, lisp, <insert your favorite dynamic language here>, etc. But nobody here is saying "Let's give up ruby and switch to Javascript!" Popularity is not everything.
(It's also worth noting that Objective-C itself may well be as popular, or more so, than most of those same languages. It is, of course, a difficult thing to measure, but there is some evidence to suggest its at least more popular than languages like Lisp)
