我在JavaScript中使用模块化模式.我想知道我们是否可以阻止公共模块被覆盖.例如,在function1下面的代码中,function2,function3和function4可以在外面访问,但我不想覆盖.如果重写这些函数,那么我希望编译器生成错误消息

      function4 : function(){
          alert("this is Function4");

}());


$.function1(); //will alert - this is Function1
$.function2(); //will alert - this is Function2

/*
