ES6数组对象解构{}

<pre>//数组对象const people = [ {name:'Henry',age:20}, {name:'Bucky',age:25}, {name:'Emily',age:30},];// 需求,取靠前个age// es5var age = people[0].age;console.log(age)//20// es6解构const [age] = people;/** * 因为靠前层解构的是数组,所以会返回靠前条的整条数据 */console.log(age)//{ name: 'Henry', age: 20 }/** * 如果想拿靠前条数据的age值就得再解构一次 */const [{age}] = people;console.log(age)//20</pre>
