object create

Introduced in ES5.

在ES5中引入。

Creates a new object, with the specified prototype.

使用指定的原型创建一个新对象。

Usage:

用法：

const newObject = Object.create(prototype)

Example:

例：

const animal = {}const dog = Object.create(animal)

The newly create object will inherit all the prototyope object properties.

新创建的对象将继承所有原型对象的属性。

You can specify a second parameter to add new properties to the object, that the prototype lacked:

您可以指定第二个参数以向原型添加缺少的新属性：

const newObject = Object.create(prototype, newProperties)

where newProperties is an object of objects that define each property.

其中newProperties是定义每个属性的对象的对象。

Example:

例：

const animal = {}const dog = Object.create(animal, {  breed: {    value: 'Siberian Husky'  }});console.log(dog.breed) //'Siberian Husky'

I didn’t just say breed: 'Siberian Husky' but I had to pass a property descriptor object, defined at the beginning of this page.

我不只是说breed: 'Siberian Husky'而是我必须传递在页面开头定义的属性描述符对象。

Object.create() is often used in combination with :

Object.create()通常与结合使用：

const dog = Object.assign(Object.create(animal), {  bark() {    console.log('bark')  }})
