AngularJS

AngularJS is a discontinued, open-source JavaScript framework by Google designed to extend HTML for building powerful single-page applications using MVC or MVVM patterns, offering data binding, dependency injection, and testability to simplify development. AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade/Pug and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control.
