javascript - Object.create 未按预期工作

Question

我不确定为什么这段代码不起作用。我正在尝试Object.create();改用new

var Car = function() {
   console.log('Car Consctructor');
};

Car.prototype.color = 'red';

var bmw = Object.create(Car);

console.log(bmw.color); //Doesn't log red - ??

Answer 1

Car是一个函数，Object.create()需要一个原型。

var bmw = Object.create(Car.prototype);

Answer 2

你将不得不prototype通过Object.create

var bmw = Object.create(Car.prototype);
