# 🏅 DAY13 每日任務
###### tags: `JS 直播班 - 2021 秋季班`

前情提要
---
#### 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 key 的值帶有小數點或是空格時可以使用 (如 -- some.data)，記得要加上引號 (單引號或雙引號皆可)
obj['key'] = value;  // 新增或修改
console.log(obj['key']); // 取得

如果屬性一開始就存在，則以上的語法會更新該屬性的值; 反之則會建立一個新的屬性。

問題
---
請透過 console.log ，嘗試透過前面所介紹的 2 種方法依序輸出以下屬性:

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
console.log(); 

// 取得 "PM2.5" 的值
console.log();

// 取得 isSunny 的值
console.log(); 

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

// 在 rainFall 新增一個屬性名為「旗津」、設定值為 200，並輸出答案
<!-- 程式碼撰寫處 -->
console.log();

回報流程
---
將答案寫在 CodePen 並複製 CodePen 連結貼至 thread 中回報就算完成了喔! 解答請參考下圖（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.旗津);

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