Javascript 中new 操作符后面的构造函数带括号和不带括号的区别是什么？ 怎么理解不带括号的？

网上博客看到的习题：

1.

function Class(){
}
Class.prototype=Class;
Class.__proto__.prop=1
alert((new Class).prop);    // 1

2.

function Class(){
}
Class.prototype.__proto__.prop=1;
Class.prototype=new Class;
alert((new Class).prop);    // 1

 怎么理解上面两道题中的new Class ？  求解答，谢谢！！！

Answer 1

带括号是调用，不带是引用
