当我的数组中只有一个对象时，控制台显示4个对象的信息

Question

我在 angularjs 中有以下代码：

TimeSlotsModel.all()
            .then(function (result) {
                vm.data = result.data.data;

                var events = [];

                 angular.forEach(vm.data, function(value,key) {

                    var eventName = value.name;
                    var startDate = new Date(value.startDate);
                    var endDate = new Date(value.endDate);

                    var selectedStartingTime =new Date(value.startTime * 1000 );
                    var selectedEndingTime = new Date(value.endTime * 1000);

                    //timing is not right, needs fixing
                    startTime = new Date(startDate.getFullYear(), startDate.getMonth(), startDate.getDate(),selectedStartingTime.getHours(), selectedStartingTime.getUTCMinutes());
                    endTime = new Date(endDate.getFullYear(), endDate.getMonth(), endDate.getDate(),selectedEndingTime.getUTCHours(), selectedEndingTime.getUTCMinutes());                     
                    // console.log(startTime);
                    events.push({
                        title: 'Event -' + eventName,
                        startTime: startTime,
                        endTime: endTime,
                        allDay: false

                    });

            console.log(eventName);
            console.log(events);
            // console.log(value);

             //value is the object!!
            })
             return events;
             $scope.$broadcast('eventSourceChanged',$scope.eventSource);

            })

         }

每次forEach循环遍历我的对象数组vm.data时，控制台都会打印出来：

我的问题是：

1）为什么要打印4个对象的细节？这是否意味着对于数组中的每个对象，它包含4个其他对象？

2）每个对象是否正确推送到事件[]？

3）如果问题2的答案是否定的，我该怎么做才能解决它？

编辑：更新了使用promise返回事件数组的代码：

    //Calendar Controller
  .controller('CalendarCtrl', function ($scope,TimeSlotsModel,$rootScope,$q) {
    var vm = this;


    function goToBackand() {
        window.location = 'http://docs.backand.com';
    }

    function getAll() {
        TimeSlotsModel.all()
            .then(function (result) {
                vm.data = result.data.data;
            });
    }

    function clearData(){
        vm.data = null;
    }

    function create(object) {
        TimeSlotsModel.create(object)
            .then(function (result) {
                cancelCreate();
                getAll();
            });
    }

    function update(object) {
        TimeSlotsModel.update(object.id, object)
            .then(function (result) {
                cancelEditing();
                getAll();
            });
    }

    function deleteObject(id) {
        TimeSlotsModel.delete(id)
            .then(function (result) {
                cancelEditing();
                getAll();

    //rootScope refers to the universal scope, .$on is a receiver for the 
    //message 'authorized'
    $rootScope.$on('authorized', function () {
        vm.isAuthorized = true;
        getAll();
    });

    $rootScope.$on('logout', function () {
        clearData();
    });

    if(!vm.isAuthorized){
        $rootScope.$broadcast('logout');
    }

    initCreateForm();
    getAll();


    $scope.calendar = {};
    $scope.changeMode = function (mode) {
        $scope.calendar.mode = mode;
    };

    $scope.loadEvents = function () {
        $scope.calendar.eventSource = getEvents();
        $scope.$broadcast('eventSourceChanged',$scope.eventSource);

    };

    $scope.onEventSelected = function (event) {
        console.log('Event selected:' + event.startTime + '-' + event.endTime + ',' + event.title);
    };

    $scope.onViewTitleChanged = function (title) {
        $scope.viewTitle = title;
    };

    $scope.today = function () {
        $scope.calendar.currentDate = new Date();

    $scope.isToday = function () {
        var today = new Date(),

            console.log(deferred.promise);


         }

我相信詹姆斯就在这里，控制台可能是罪魁祸首，我只是重现了同样的行为。
