Difference between $scope and $rootScope

Question

Can anyone explain the difference between $scope and $rootScope?

I think

$scope:

We can get ng-model properties in particular cont

Answer 1

In other way we can look at this; $rootScope is global while $scope is local. When Controller is assigned to a page, so a $scope variable can be use here because it binds to this controller. But when we want to share its value across to other controllers or services, then $rootScope is being used (**there are alternative ways, we can share values across but in this case we want to use $rootScope).

Your second question about how you define those two words are correct.

Lastly a bit off track, please use $rootScope with care. Similar to the way you use global variables, can be a pain to debug and you may accidentally change the global variable somewhere inside a timer or something which makes your reading incorrect.
