Summary

AngularJS services are singleton objects that you can register with the dependency injector; controllers and other AngularJS components, including other services, can consume them. AngularJS provides much of the back-end functionality in the way of services, such as $http, which enables you to easily integrate web server communication into your AngularJS applications.

In this chapter you also learned about several of the built-in services, such as $cookieStore, $q, $window, $location, $animate, and $cacheFactory. These and other AngularJS services can be used to easily inject functionality into your controllers, directives, and custom services.
