# 🏅 Day 15 - 陣列物件整合操作應用
### 題目
請依照下方程式碼中註解的要求完成這段程式碼（補上 `...` 的部分）：
```javascript=
let productInfo = {
price: 1000, // 購買價格
coupons: [
{
due_date: "2022-10-15", // 到期日
id: 123,
is_enabled: 0, // 是否啟用
percent: 0.7, // 折扣比例
title: "特惠七折", // coupon 標題
},
{
due_date: "2022-08-08", // 到期日
id: 456,
is_enabled: 1, // 是否啟用
percent: 0.5, // 折扣比例
title: "特惠五折", // coupon 標題
}
]
};
/* 請取得 coupons 陣列中 id 為 456 的 percent，並賦值給 discountPercent */
let discountPercent = ...;
/* 請取得 coupons 陣列中 id 為 456 的 title，並賦值給 title */
let title = ...;
/* 請修改 coupons 陣列中 id 為 456 的 到期日，將其延後兩日（至 2022-08-10）*/
...
/* 請取得 coupons 陣列中 id 為 456 的 is_enabled，並填入以下 if 判斷式中;
如果判斷為 true，則對「購買價格」進行折扣 */
if(...) {
/* 程式碼撰寫處，對「購買價格」進行折扣 */
...
console.log(`優惠券「${title}」已啟用`);
} else {
console.log("優惠券未啟用");
}
console.log(`購買價格 ${productInfo.price}`);
```
