This concludes our first chapter. To quickly summarize, we went about building our Address Book App and in doing so learned about the various AngularJS directives such as ng-app and ng-repeat. We saw how two-way data bindings and expressions work and the importance of scope. We also saw how we can hide and show certain elements using the ng-show and ng-hide directives. Last but not least, we used some simple and easy CSS3 features to style our app.

In the next chapter, we will see the various tools that frontend developers should ideally have in their toolbox and how to go about using them.
