对象与数组的解构赋值

// 数组的解构
let [uname, email] = ['杨过', '123456@qq.com']
console.log(uname, email)
;[uname,...arrs] = ['小龙女', '123456@qq.com' , '女']
console.log(uname,...arrs)
console.log('---------------------------------------')
//对象的解构
let show = (user) =>`${user.uname}: ( ${user.email} )`
let user = { uname: '盖伦', email: '123456@qq.com' }
console.log(show(user));
console.log('---------------------------------------')
// 使用对象解构对上面代码进行重写
show = ({username,email}) => `${username}: ( ${email} )`
user = { username: '盖伦', email: '123456@qq.com' }
console.log(show(user));
console.log('---------------------------------------')
// 访问器属性
