We can retrieve the $rootScope from the DOM by selecting the element where the ngApp directive is placed and wrapping it in an Angular element (using the angular.element() method). We should never rely on fetching element properties from a DOM element during the lifecycle of an application. The techniques are presented as techniques for debugging purposes. Although not always necessary nor a first step, we can get access to the Angular properties that are attached to any DOM element. We can use these properties to peek into how the data is flowing in our application. The contextual part plays a big role here, as it allows us to set breakpoints in the application to stop the process, and direclty start exploring our current context from the REPL.
