# 🏅 5/24(二) 每日 JS 刷題任務 - 從不同資料集，尋找規律性

### 題目一：判斷是否有值
* 判斷帶入參數是否有陣列中的值

const numAry = [1,3,4,6,8];

// input 輸入
checkNum(3)
checkNum(9)
checkNum(83)
checkNum(6)

// output 輸出 obj 的結果
true
false
false
true

### 題目二：刪除值
* 判斷陣列是否有值，有則刪除指定資料，並回傳 `deletAry` 變數
* 沒有則回傳 false

const deletAry = [1,3,4,6,8];

// input 輸入
delNum(3)
delNum(9)
delNum(83)
delNum(6)

// output 輸出 obj 的結果
[1,4,6,8]
false
false
[1,4,8]

### 題目三：兩個陣列尋找相同數字
* 請找出 a 與 b 陣列裡面，若有相同數值，則篩選出來成為一個陣列

const a = [1,3,4,6,8];
const b = [3,6,12];
// input 輸入
checkSame(a,b)


// output 輸出 obj 的結果
[3,6]
