angularjs - 设置 $rootScope.$state = $state; 的目的是什么？使用angular-ui ui-router？

Question

我的代码如下:

var app = angular.module('app', ['admin', 'home', 'questions', 'ui.compat', 'ngResource', 'LocalStorageModule']);

app.run(['$rootScope', '$state', '$stateParams', function ($rootScope, $state, $stateParams) {
        $rootScope.$state = $state;
        $rootScope.$stateParams = $stateParams;
        $state.transitionTo('home');
    }]);

有人可以解释一下以 $rootScope 开头的两行是做什么的吗？他们需要吗？

此评论摘自项目 github 页面上的示例源代码:

It's very handy to add references to $state and $stateParams to the $rootScope so that you can access them from any scope within your applications. For example, <li ng-class="{ active: $state.includes('contacts.list') }"> will set the <li> to active whenever 'contacts.list' or one of its decendents is active.
