AngularJS Essentials

Be aware that depending on the size of the application, the broadcast through
$rootScope may become too heavy due to the number of objects listening to the

Chapter 5
There are a number of libraries that implement the publish and subscribe pattern
in JavaScript. Of them, the most famous is AmplifyJS, but there are others such as
RadioJS, ArbiterJS, and PubSubJS.
Summary
In this chapter, we studied what exactly $scope and $rootScope are and how the
two-way data binding mechanism works. Also, we went through some of the best
practices about using the scope, and we discovered its broadcasting mechanism.
In the next chapter, we are going to understand how to break up our application
into reusable modules.
