Ember.js is a new JavaScript framework that was formerly SproutCore 2.0. When I tried out SproutCore for the first time a few years ago, I was impressed with it’s data binding and templates, but I found it included a lot of things I didn’t need or want, like a large UI framework and it’s own recommended toolchain and workflow. I wished I could just use the few core parts of SproutCore easily and leave out the rest. Ember.js is that wish coming true. Its main focuses are: data binding, computed properties, and auto-updating templates.

Check out the Ember.js on Github and read the announcement here.

Ember.js had the code name Amber while in development. It was announced under the name Amber.js, but renamed to Ember.js after there was some confusion with another project
