ES6_对象简洁语法_note

• 对象简洁语法,如:

<script > let name = 'kirin'; let age = 18; let json = {
     // 前面是简写 name,// name:name, age,// age:age, } console.log(json); </script>

方法简写:

<script > let name = 'kirin'; let age = 18; let json = {
     name,// name:name, age,// age:age, /*showA: function () { return this.name; },*/ //等价于上面的写法 showA() {
     return this.name; }, } </script>

简洁语法中不要写箭头函数:

<script > // 千万不要在里面用箭头函数,因为已经使用了简写,而且使用箭头函数的话,箭头函数内的对象并没有指定 let name = 'kirin'; let age = 18; let json = {
     name,// name:name, age,// age:age, showA: () => {
     return this.name; } } console.log(json.showA()); </script>

对象简洁语法:

<script > let x = 10; let y = 20; function show({
    x, y}) {
     console.log(x, y); } show({
    x: 10, y: 20}) </script>
