Closure Library

What is the Closure Library?

The Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. You can pull just what you need from a large set of reusable UI widgets and controls, and from lower-level utilities for DOM manipulation, server communication, animation, data structures, unit testing, rich-text editing, and more.
The Closure Library is server-agnostic, and is intended for use with the Closure Compiler.

What can the Closure Iibrary do for me?

If you are developing a large or growing application, you may benefit from the Closure Library's breadth. A well-tested library can insulate you from cross-browser compatibility issues and the minutiae of client-side programming, letting you focus on the fun stuff.
