javascript - js 销毁子对象内部对象

Question

我分配一个对象:

const info = { name: 'Peter', location: { province: 1, city: 2 } };
let { name } = info;
console.log(name); // 'Peter'

// then how to get location.province
let { 'location.province': province } = info;
console.log(province); // 'undefined'

如何通过解构获取子对象location.province？？？

Answer 1

通过进行“嵌套”解构:

let {name, location: {province}} = info;

对于此类问题，请务必先查看 MDN，因为它通常是 has many examples 。
