# 🏅 JS 任務 Day10 - 陣列 + 物件
> 建議觀看的影音章節：
> JS - 陣列教學
> JS - 物件教學
### 題目一：依照文字描述物件
請宣告一個 `family` 的變數，賦予物件型別，並嘗試在裡頭加上以下資訊
* 母親叫做`Mary`
* 父親叫做 `Bob`
* 有三個孩子，分別叫做 `John`、`Tom`、`Kate`
* 養了五隻貓、七隻狗、八頭牛、九隻蜘蛛
* 房貸是否繳清：否
### 題目二：看圖設計物件
* 請宣告一個 `room` 的變數，賦予物件型別，盡量描述下方圖片內容，例：有多少人開會，男女比例、文具數量等等。
### 題目三：擴充物件內容
* 請透過 `addKeyValue` 函式，來增減 `obj` 物件內容。
``` =JavaScript
const obj = {
name: "",
people:3
};
// input 輸入
addKeyValue("name","Mike")
addKeyValue("people",2)
addKeyValue("people",4)
// output 輸出
//1
{
name:"Mike",
people:3
}
//2
{
name:"Mike",
people:5
}
//3
{
name:"Mike",
people:9
}
```
### 題目四：進階題，不適合新手
請宣告一個 `obj` 函式，並用`obj()[2]()`方式執行，並會 return 回傳 "hi"
```
obj()[2]()
// output 輸出
"hi"
```
