The prototype (parent class) of a prototype object in Javascript?

Question

In Javascript, I can obtain the prototype of Array object by

var arr_prototype = Array.prototype

As I understand, this Array.prototype is similar to a Class in OOP.

In a pure OOP language, the Array class may inherit from Iterable class, and Iterable class may inherit from Object class.

So I wish to see the parent class of arr_prototype by eval the expression arr_prototype.prototype .

However, it returns undefined . Does anyone have ideas about this?

Answer 1

Object.getPrototypeOf(arr_prototype );

prototype属性不属于实例，它属于构造函数
