🆚 jQuery vs. YUI

jQuery is a fast, small, feature-rich JavaScript library designed to simplify HTML DOM tree traversal and manipulation, event handling, CSS animations, and Ajax.

It provides a cross-browser selector engine, formerly known as Sizzle, supports deferred and promise objects for asynchronous workflows, has built-in JSON parsing and utility functions, and allows extensibility through a large ecosystem of plugins.

YUI is a legacy, open-source JavaScript and CSS library for building interactive web applications with a focus on modular architecture and cross-browser consistency.

It includes over 30 modules covering DOM manipulation, event handling, animations, data utilities, and UI components, and provides a dependency management system with dynamic module loading.
