Managing State in Angular Apps
State management in large, complex applications has been a headache plaguing AngularJS / Angular developers over the last few years. In AngularJS (version 1.x), state management is often addressed using a confusing mixture of services, events, and
$rootScope. In Angular (versions 2+), component interaction is cleaner but can still be quite involved, encompassing many different approaches depending on the desired direction of the flow of data.
Note: In this article, AngularJS refers specifically to version 1.x of the framework while Angular refers to versions 2.x and up, as per the Branding Guidelines for Angular.
