angularJS using TypeScript the difference between the following methods -

could please explain difference between 2 methods load controllers,service.... etc

     var appmodule = angular.module("myapp", []);      appmodule.controller("mycontroller", ["$scope", ($scope)       => new application.controllers.mycontroller($scope)]); 

---

 module todos {       'use strict';    var todomvc = angular.module('todomvc', [])         .controller('todoctrl', todoctrl)         .directive('todoblur', todoblur)         .directive('todofocus', todofocus)         .service('todostorage', todostorage);    } 

the first method dependency injection inline. second method depends on $inject/constructor argument being setup in controller.
