解构赋值

//数组解构
        const f4 = [小白, 小黄, 小黑, 小花];
        let [bai, huang, hei, hua] = f4;
        console.log(bai);
        console.log(huang);
        console.log(hei);
        console.log(hua);

//对象解构
        const Bird = {
            naim: "niao",
            age: 1,
            fly: function() {
                console.log("我会飞......");
            }
        }

        let {
            name,
            age,
            fly
        } = Bird;
        console.log(name);
        console.log(age);
        console.log(fly);
        fly();
