jQuery has plugins.

Lots of them, in fact. The jQuery plugin page lists hundreds of additions to the base jquery package. These plugins make web development even easier and more glamorous than jQuery alone, doing splendid things like Show dialogs.

Now isn’t that cool? jQuery plugins let external authors write neat libraries to extend the language, much as firefox extensions improve the core of firefox. As jQuery has become the javascript go-to tool of choice, jQuery plugins have become the library tools of choice for productive, external-library-oriented developers, such as you and me. So fly, ye’ programmer, and explore the world of jQuery plugins.
