AngularJS lets you write client-side web applications as if you had a smarter browser. It lets use good old HTML (or HAML, Jade and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly

Universal video embed.
Turn ES6 code into readable vanilla ES5 with source maps
Realtime application framework for Node.JS, with HTML5 WebSockets and cross-browser fallbacks support.
