# 🏅 Day 7 - 加總技巧、Bootstrap 格線系統 1
題目（使用 CodePen 作答）
---
小明有固定存錢的好習慣，以下是小明的銀行帳戶資訊。
1. 請協助他將存款資訊 mingTransfer 的內容合併到 mingAccount.depositRecord 陣列中（使用 `.push()`）。
2. 請將他各月的存款累加到 mingAccount.deposit 中（可以使用 `forEach()` 或 `reduce()`）
參考: https://developer.mozilla.org/zh-TW/docs/Web/JavaScript/Reference/Global_Objects/Array/Reduce
```js=
// 小明的銀行帳戶資訊
let mingAccount = {
name: '小明',
age: 22,
deposit: 10000,
depositRecord: [
{
title: '開戶',
amounts: 10000
}
]
};
// 小明的存款資訊
let mingTransfer = [
{
title: '一月存款',
amounts: 777
},
{
title: '二月存款',
amounts: 7000
},
{
title: '三月存款',
amounts: 70000
}
]
console.log(mingAccount);
```

觀看 [Bootstrap 網格](https://bootstrap5.hexschool.com/docs/5.1/layout/grid/#row-columns)，練習運用 `.row` `.col-*`，修改此 [Codepen](https://codepen.io/hexschool/pen/NWzByya) 中 `...` 的部分，還原成下方圖片樣式
## 回報流程
將答案寫在 CodePen 並複製 CodePen 連結貼至底下回報就算完成了喔!
解答位置請參考下圖（需打開程式碼的部分觀看）
<!-- 解法一
mingTransfer.forEach(item => {
mingAccount.depositRecord.push(item);
mingAccount.deposit += item.amounts;
})
console.log(mingAccount);
-->
<!-- 解法二
mingTransfer.forEach(item => {
mingAccount.depositRecord.push(item);
})
mingAccount.deposit = mingAccount.depositRecord.reduce((prev, curr) => {return prev + curr.amounts}, 0);
console.log(mingAccount);
-->
