# 🏅 Day 05 - 賦值運算子與傳參考概念

### 題目

以下兩題請合併為一份 CodePen 繳交，並透過「註解」進行回答。

問題一
---
了解賦值運算子，並計算出最後 console.log 印出的結果

let a = 1;
let b = 2;
a += 30;
a--;
b - 1;
a -= b;

console.log(a);
console.log(b);

問題二
---
請回答以下程式碼最後的 console.log 結果

let groupA = {
  people: 10,
  age: 20
};

let groupB = groupA;
groupB.people = 3;

console.log(groupA);

## 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）


<!-- 解答：

問題一：
a: 28
b: 2
（陷阱：b - 1 那行並未賦值，
所以其值並不會帶入 b）

問題二：
{
people: 3,
age: 20
}
