function Phone(brand, price) {
this.brand = brand
this.price = price
}
Phone.prototype.call = (function() {
console.log(‘打电话请给我’)
})

    function SmartPhone(brand, price, color, size) {
        Phone.call(this, brand, price)
        this.color = color
        this.size = size
    }
    SmartPhone.prototype = new Phone
    SmartPhone.prototype.constructor = SmartPhone

    SmartPhone.prototype.photo = function() {
        console.log('拍照')
    }
    SmartPhone.prototype.playGame = function() {
        console.log('玩游戏')
    }
    const chuizi = new SmartPhone('锤子', 3333, '红色', '3.3yincun')
