This document discusses how to work with AngularJS by breaking down a large monolithic web application into smaller reusable components. It describes that the original application had over 10 JavaScript files and over 2500 lines of code total. By adopting AngularJS, the application was broken into components with two-way data binding, modularity, templates and dependency injection which simplified the code and made it easier to support. The document concludes that using AngularJS allows for simple page building, reusable components, easy support and more confident code.
