ES6第4回-变量解构赋值

<script>
        
            //ES6 允许按照一定模式从数组和对象中提取值，对变量进行赋值
            //称为解构赋值
            //1、数组的解构
            const F4 = ['A','B','C','D'];
            let [a,b,c,d] = F4;
            console.log(a);
            //2、对象的解构
            const zhao = {
                name:"赵本山",
                age:"不详",
                xiaoping:function(){
                    console.log('演小品');
                }
            }
            // let {name,age,xiaoping} = zhao;
            // console.log(name); // 赵本山
            let {xiaoping} = zhao;
            xiaoping(); //演小品
