Where is rootScope values are stored? In cookie or local storage?

Question

Where is `rootScope` values are stored? In cookie or local storage?

I have a small doubt about rootScope in angularjs.

I have passing a value between two controllers, So I have using the $rootScope.

I want to know how to rootScope Working? and where is the rootScope data stored?
In Local Storage or cookie or anything else?

You can say $rootScope is like a global variable within scope of angular stored in scope of page. — Nikhil Aggarwal, Jun 19 '15 at 13:14
It's just stored in memory, basically like a global variable. It will not survive a full page reload (F5) — HaukurHaf, Jun 19 '15 at 13:17

When switching controllers (or routes or states) in AngularJS only what's inside the controller closure is destroyed, anything outside of it is not. $rootScope is a service instantiated only once on the page so when you switch controllers it is not destroyed. That's why it's persistent. If you reload the whole page (hit [F5] in your browser) then everything in it is lost.

This is something fundamental for the whole Single Page Application pattern.

If you look into the sources for this service you won't find anything related to cross-page persistence.
