陣列解構

將family的值一一賦予到變數上

//原本寫法

let family = ['小明', '杰倫', '阿姨', '老媽', '老爸']

let ming = family[0];
let jay = family[1];
let auntie = family[2]
let mom = family[3];
let dad = family[4];

let family = ['小明', '杰倫', '阿姨', '老媽', '老爸']

//直接把變數放進陣列中
let [ming, jay, auntie, mom, dad] = family

若數量不對等，後面沒有的值就不會被複製過來

let [ming, jay, auntie] = family

//小明 杰倫 阿姨

若是中間的值沒給，記得留空值

let [ming, jay, , mom, dad] = family

//小明 杰倫 阿姨 老媽 老爸

物件解構

let Team = {
	ming: '小明',
	jay: '杰倫',
}

let { ming } = Team
//小明

let { ming: minggg } = Team //可以重新給變數一個名稱，並把值賦予到那個名稱上
console.log(minggg) //小明
