ANGULARJS

Website: angularjs.org
GitHub: github.com/angular/angular.js

The first thing we have to mention to avoid confusion. AngularJS and Angular are two different frameworks. AngularJS is based on JavaScript and Angular uses TypeScript as the foundation (we’ll talk about it next.)

AngularJS was created back in 2009 and brought two-way data binding, which helps us see the data updates in JavaScript in UI automatically. Also, AngularJS allows developers to write apps in MVC (Model-View-Controller) architecture in a simpler way. Its dependency injection feature also helps to keep the project code maintainable and easy to test. 

AngularJS that is maintained by Google, as well as 1,500+ contributors on GitHub, is often used to create single-page applications.
