JavaScript 销毁对象
示例
销毁是将对象的属性提取为变量的便捷方法。
基本语法：
let person = {
name: 'Bob',
age: 25
};
let { name, age } = person;
//相当于
let name = person.name; //鲍勃
let age = person.age; //25销毁和重命名：
let person = {
name: 'Bob',
age: 25
};
let { name: firstName } = person;
//相当于
let firstName = person.name; //鲍勃使用默认值进行销毁：
let person = {
name: 'Bob',
age: 25
};
let { phone = '123-456-789' } = person;
//相当于
let phone = person.hasOwnProperty('phone') ?person.phone: '123-456-789'; //'123-456-789'使用默认值进行销毁和重命名
let person = {
name: 'Bob',
age: 25
};
let { phone: p = '123-456-789' } = person;
//相当于
let p = person.hasOwnProperty('phone') ?person.phone: '123-456-789'; //'123-456-789'
