从Object调用Object.Prototype中的函数

Question

我使用Object.prototype.func = function () {...}向Object.prototype添加了一个函数，但是当我尝试使用Object.func()对其进行调用时，会引发错误，该错误未在Object中定义。

Answer 1

Everything in JavaScript is an object and inherits from Object (including Object). If there's a property on Object.prototype then EVERYTHING can access it because it is in everything's prototype.

Answer 2

Seems to be working fine for me (from node REPL):

Object.prototype.something = function() { console.log("Something!"); }
[Function]
> b = new Ob
Object  

Object  

> b = new Object()
{}
> b.something()
Something!
