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); ``` Bootstrap 格線系統 --- 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
