# 🏅 Day 14 - 物件取值

在物件內新增、修改、取得屬性的方法有以下兩種:

1. 點記法 (Dot notation)

let obj = {};
obj.key = "value";  // 新增或修改
console.log(obj.key); // 取得

2. 括弧記法 (Bracket notation)

let obj = {};

// 當屬性的值帶有小數點、空格或是數字時可以使用，記得要加上引號 (單引號或雙引號皆可)
obj['k e y'] = "value";  // 新增或修改
console.log(obj['key']); // 取得

### 題目

請觀看下方程式碼，依照註解敘述完成程式碼（補上 `...` 的部分）：

let weather = {
  country: "高雄",
  "PM2.5": 35,
  isSunny: false,
  rainingRegion: ['鼓山', '鹽埕', '旗津'],
  rainFall: {
    鼓山: 400,
    鹽埕: 300,
  }
} 

// 取得 country 的值，並使用 console.log 印出
console.log(...); 

// 取得 "PM2.5" 的值，並使用 console.log 印出
console.log(...);

// 取得 isSunny 的值，並使用 console.log 印出
console.log(...); 

// 取得 rainingRegion 陣列的第一個值 '鼓山'，並使用 console.log 印出
console.log(...); 

// 在 rainFall 新增一個屬性名為「旗津」、設定值為 200，並，並使用 console.log 印出 rainFall 的值
...
console.log(rainFall);

## 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：

// 取得 country 的值
console.log(weather.country); // 方法一
console.log(weather["country"]); // 方法二

// 取得 "PM2.5" 的值
console.log(weather["PM2.5"]);

// 取得 isSunny 的值
console.log(weather.isSunny); // 方法一
console.log(weather["isSunny"]); // 方法二

// 取得 rainingRegion 陣列的第一個值 '鼓山'
console.log(weather.rainingRegion[0]);

// 在 rainFall 新增一個屬性名為「旗津」、設定值為 200，並輸出結果
weather.rainFall.旗津 = 200; // 方法一
console.log(weather.rainFall);

weather["rainFall"]["旗津"] = 200; // 方法二
console.log(weather["rainFall"]);
