Question

我写了三个函数如下。我把amp.js和dish.js放在一个包里。

amp.js：

var amp = (function() {
  //return ("This is a message from the demo package");

  function amp(){
      this.id=10;
  }
  amp.prototype.display=function(){  
      return 'value of id is';
  } 

}());

exports.amp =amp;

dish.js：

var cc=require('./amp');
exports.amp=cc.amp;

EX.js：

var builder = require('botbuilder');
var just=require('JUST');
console.log(just);
var amp= new just.amp();
console.log(amp);
//var ww=new builder.ConsoleConnector();

// Create bot and bind to console
var connector = new builder.ConsoleConnector().listen();
var bot = new builder.UniversalBot(connector);

bot.dialog('/', function(session){
    session.send("hello this is chat bot");
    //session.send("string returned from the %s",just.amp.display);
});

在EX.js中我试图将amp.js作为类构造函数访问，我收到以下错误，

E:\bot-prac\EX.js:4
var amp= new just.amp();
         ^

TypeError: just.amp is not a function
    at Object.<anonymous> (E:\bot-prac\EX.js:4:10)

在Node JS中导出一个类
