JS libraries on the client-side are currently stagnating and will soon be dead, largely, because they won. bind, each, map, filter, etc are now part of the language, with more coming in Harmony. They are becoming less and less necessary. Even animation, the very thing that got them started, can now be done in CSS3. There's no need to include them.
