Polymer is a new type of library for the web, built on top of Web Components, and designed to leverage the evolving web platform on modern browsers.
Polymer is comprised of two efforts:
- A set of core platform features (Shadow DOM, Custom Elements, MDV). Initially, these core features will be enabled with a set of polyfills. As browsers begin to implement these new primitives, the polyfill platform layer becomes smaller and better over time.
- A next-generation web application framework built upon these core technologies called the Polymer.
