# 🏅 5/16(一) 每日 JS 刷題任務 - 陣列設計

### 題目一：陣列長度計算

// input 輸入
checkLength([1,2,3])
checkLength([5,8,39,1,2,3])
checkLength([])

// output 輸出
3

0

### 題目二：增減陣列內容
* 請透過 `aryControl` 函式，來增減 `ary` 陣列內容。

const ary = [];
// input 輸入
aryControl("增加","black")
aryControl("增加","red")
aryControl("增加","white")
aryControl("增加","blue")
aryControl("刪除指定筆數",3)
aryControl("刪除指定筆數",1)

// output 輸出
["black"]
["red","black"]
["white","red","black"]
["blue","white","red","black"]
["blue","white","black"]
["white","black"]

### 題目三：for+陣列相加產生器，邏輯思考題
* 請嘗試用 `numAry` 變數，並搭配 `addAry` 函式來解此題目

const numAry = [1,2,3,4,5]
// input 輸入
addAry(1);
addAry(2);
addAry(3);
addAry(4);
addAry(5);
// output 輸出
