Every application has a single root scope. All other scopes are descendant scopes of the root scope. Scopes provide separation between the model and the view, via a mechanism for watching the model for changes. They also provide an event emission/broadcast and subscription facility. See the developer guide on scopes.

Is setting the value of rootScope.angular a code smell?

$rootScope._ = $window._;
$rootScope.angular = $window.angular;
