Common usage of $rootScope

In app.js

'use strict'// run 的作用表示初始化执行，也就是所以页面加载之前执行angular.module('app',['ui.router']).run(['$rootScope',function($rootScope){
     //比如说我们在所有页面初始化执行之前添加一个im属性，那么之后创建的所有$scope对象因为都是它的子孙对象，都会有im这样的属性
     $rootScope.im = function(){
         console.log('im');
     }
}]);

This is the biggest role of $rootScope, which is equivalent to defining public functions and variables. However, we still recommend using services to generally define public functions.
