js

const prototype = {
  getName() {
    return `first-name: ${this.firstName}, last-name: ${this.lastName}`
  },
  say() {
    console.log('love you')
  }
}

// 克隆自己，生成一个新的对象
// Object.create()用到了原型模式的思想
// 基于一个原型创建一个对象

let x = Object.create(prototype)
x.lastName = 'shulu'
x.firstName = 'lqy love'

x.say() //love you
console.log('x.getName() :', x.getName())

//打印为 x.getName() : first-name: lqy love, last-name: shulu
