The YUI App Framework, developed by Yahoo! and the YUI community, offers a modular architecture and a fast, efficient foundation for frontend-heavy web applications. It utilizes an MVC-like structure for data management and provides extensive documentation for ease of use. The framework is designed to be configurable with reasonable defaults, supporting rapid application development.
