# 🏅 Day 11 - 物件參考

### 物件參考觀念（關鍵字：JS 深拷貝、淺拷貝差異）

題目
---
(1)
1-1. 請問以下的輸出結果為何？
1-2. 如果希望 `console.log(obj === objNew);` 的結果為 false，則可以如何修改？

let obj = {
    title: '錢錢',
    amounts: 66666,
}
let objNew = obj;
objNew.amounts = 123;
console.log(obj.amounts); // 輸出結果為何？
console.log(obj === objNew); // 輸出結果為 true 還是 false？

(2)（陷阱題！，需要用深拷貝處理）
2-1. 請問以下的輸出結果為何？
2-2. 如果希望調整 `objNew.innerObj` 時不會影響到 obj，則可以如何修改？

let obj = {
    title: '錢錢',
    amounts: 66666,
    innerObj: {
    	title: '私房錢',
      amounts: 1000
    }
}
let objNew = {...obj};
console.log(obj === objNew); // 輸出結果為 true 還是 false？
objNew.innerObj.amounts = 2000;
console.log(obj.innerObj.amounts); // 輸出結果為何？

解答位置請參考下圖（需打開程式碼的部分觀看）


<!-- 解答：

(1)
1-1.
console.log(obj.amounts) // 123
console.log(obj === objNew) // true

1-2.
// 淺拷貝
可以將 let objNew = obj; 修改為
a. let objNew = {...obj};
b. let objNew = Object.assign({}, obj);

// 深拷貝
let objNew = JSON.parse(JSON.stringify(obj));

(2)
2-1.
console.log(obj === objNew); // 結果為 false
objNew.innerObj.amounts = 2000;
console.log(obj.innerObj.amounts); // 結果為 2000

2-2.
// 深拷貝
可以將 let objNew = {...obj}; 修改為
let objNew = JSON.parse(JSON.stringify(obj));
