Practically everything I can think of needing on a daily basis has a solution already made and tested in jQuery. Very rarely do I have to reinvent the wheel, be it tablesorting, an AJAX-sourced type-ahead box, or a nicer date widget. That saves time and effort. Its ubiquity also means that problems are often already solved in it. Every time I've run into a jQuery bug there has been discussion and work-arounds already posted online by people much smarter than myself.
