I'd be the last to say that Javascript doesn't have its proper place, all of the sites I'm working on use it to some extent.
But I'd not call it 'good enough' as in a replacement for all those other programming languages that make up todays palette, it is simply good enough for its intended purpose, which is to extend web pages to include features for which tags are too limiting, including underwater communication with a web server in order to make dynamic changes to a page that has already been served.
JavaScript to me is a means to an end, definitely not a general purpose programming language. Though technically you can write anything in it (it's Turing complete after all).
