简单的继承

混入式继承

var person1 = {
    house: {
        address: '东京'，
        price: 1000k
    },
    car: {
       brand: '保时捷911',
       price: 1000k
    }
}
var person2 = {
    girlFriend: ['菜菜子'，'南小鸟','狂三']
}
for (var key in person1) {
    person2[key] = person1[key]
}
console.log(person2)

原型替换继承

var person1 = {
    house: {
        address: '旧金山',
        price: '2000k'
    },
    car:{
        brand: '比亚迪宋max',
        price: '2000k'
    }
}
function Rich_person(gfs) {
    this.gfs = gfs
}
Rich_person.prototype.plane = {
    price: '30000k',
    kind: 'airBus'
}
var p2 = new Rich_person(['十香'，'奈亚子'])
console.log(p2)
Rich_person.prototype = person1
var p3 = new Rich_person(['四系乃'，'康娜'])
console.log(p3)

混合式

var person1 = {
    house: {
        address: '旧金山',
        price: '2000k'
    },
    car:{
        brand: '比亚迪宋max',
        price: '2000k'
    }
}
function Rich_person(gfs) {
    this.gfs = gfs
}
Rich_person.prototype.plane = {
    price: '30000k',
    kind: 'airBus'
}
var p2 = new Rich_person(['十香'，'奈亚子'])
console.log(p2)
for (var key in person1) {
    Rich_person.prototype[key] = person1[key]
}
console.log(p2)
