Chapter 3. What you need to know about AngularJS

AngularJS is a web application framework, and its popularity has made it one of the most-used JavaScript tools available today. Ionic is built on top of Angular, so it’s important to have a grasp of how it works. Instead of having to build an entire web application framework for Ionic, it uses Angular and extends it with a large number of interface components and other mobile-friendly features.
