🆚 jQuery vs. Polymer

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.

Polymer is a legacy open-source JavaScript library created by Google for building components based on Web Components standards.

The library introduced declarative custom elements, data binding, shadow DOM helpers, and reusable component packaging, and later evolved into the Lit project focused on lightweight and faster component development.
