We started our first several entries demonstrating the core components of our application and how to set up an AngularJS app. In parts 4 and 5, we covered the internals of directives in AngularJS, and in last week’s post we discussed the power of services. In this section, we’re covering several key topics we didn’t have a chance to introduce earlier in the series. We also offer a list of great resources and the latest tools, and we’re proud to announce the impending release of our next book.
