了解JavaScript中不同类型的函数

Question

请查看下面的代码片段，其中还有一些评论（我的理解）包含在代码中。请告诉我天气我对以下功能的理解是否正确？

  function MyViewModel() {
        this.DisplayInside = function () { //Is this someting like a public method can be called out side MyViewModel
            console.log("DisplayInside");
        }
        var DisplayInside = function () { ///Is this someting like a private method can be called within MyViewModel
            console.log("DisplayInside");
        }
    }

    MyViewModel.DisplayOutSide = function () { //Is this someting like a public static method
        console.log("DisplayOutSide");
    }

       $(document).ready(function () {

          MyViewModel.DisplayOutSide(); //Call the static method
          var model = new MyViewModel();
          model.DisplayInside(); //Call the function using object
       });

有没有更好的方法在java Script中实现oops概念。
