Rivets.js - Lightweight and powerful data binding + templating solution for building modern web applications

Rivets.js is completely agnostic about your model / controller layer and works well with existing libraries that employ an event-driven model such as Backbone.js and Stapes.js. It also ships with built-in support for plain JavaScript objects, so you can use Rivets.js right away without needing a separate model or observables library.
