const person = {
isHuman: false,
printIntroduction: function () {
console.log(`My name is ${this.name}. Am I human? ${this.isHuman}`);
}
};
// 创建的是一个空对象, 该对象的__proto__属性连接到 person 对象上面
const me = Object.create(person);
console.log(me, 'me is wate') // {}
console.log(me.isHuman, '我是普通的属性') // false
me.name = 'liba'
me.isHuman = 'true'
修改 me 对象的属性并不会影响 person 对象的属性
console.log(person) // {isHuman: false, printIntroduction: ƒ}
console.log(me, 'me') // {name: "liba", isHuman: "true"}
console.log(person.printIntroduction()) // My name is undefined. Am I human? false
console.log(me.printIntroduction()) // My name is liba. Am I human? true
外面在下雨,喜欢下雨天。
