# 🏅 JS 任務 Day17 - 混合題目

### 題目一：陣列與物件排序
* 依照物件中每個人的分數大小做排序

const scoreAry = [
    {
        name:"葉子",
        score:99 
    },
    {
        name:"洧杰",
        score:60
    },
    {
        name:"卡斯伯",
        score:80
    }
];

// input 輸入
callAry("正序",scoreAry)
callAry("反序",scoreAry)

// output 
// 第一筆
[
    {
        name:"洧杰",
        score:60
    },
    {
        name:"卡斯伯",
        score:80
    },
    {
        name:"葉子",
        score:99
    }
]
// 第二筆
[
    {
        name:"葉子",
        score:99
    },
    {
        name:"卡斯伯",
        score:80
    },
    {
        name:"洧杰",
        score:60
    },
    
]

### 題目二：篩選資料
* 請篩選出第一個參數，並比對 `scoreAry2` 看有誰達到條件

const scoreAry2 = [
    {
        name:"葉子",
        score:99
    },
    {
        name:"洧杰",
        score:60
    },
    {
        name:"卡斯伯",
        score:80
    }
];

// input 輸入
callAry2(80)
callAry2(99)
callAry2(100)
// output 

葉子卡斯伯分數有在80分以上
葉子分數有在99分以上
沒有人分數在100分以上

### 題目三：選出從零到指定數字範圍裡面的質數

// input 輸入
prime(13)
prime(30)
prime(24)
prime(44)

// output  請以字串來顯示
"2,3,5,7,11"
"2,3,5,7,11,13,17,19,23,29"
"2,3,5,7,11,13,17,19,23"
"2,3,5,7,11,13,17,19,23,29,31,37,41,43"

## 回報流程

1. 將答案貼在 CodePen 並複製 CodePen 連結貼至「回報區」回報
（也可以將答案直接貼至「回報區」）


<!--解答：
題目一：
const scoreAry = [
{ name: "葉子", score: 99 },
{ name: "洧杰", score: 60 },
{ name: "卡斯伯", score: 80 },
];

function callAry(order, arr) {
const sorted = [...arr].sort((a, b) => {
return order === "正序" ? a.score - b.score : b.score - a.score;
});
console.log(sorted);
}

題目二：
const scoreAry2 = [
{ name: "葉子", score: 99 },
{ name: "洧杰", score: 60 },
{ name: "卡斯伯", score: 80 },
];

function callAry2(minScore) {
const filtered = scoreAry2.filter(item => item.score >= minScore);
if (filtered.length === 0) {
console.log(`沒有人分數在${minScore}分以上`);
} else {
const names = filtered.map(item => item.name).join("");
console.log(`${names}分數有在${minScore}分以上`);
}
}

題目三：
function prime(limit) {
function isPrime(n) {
if (n < 2) return false;
for (let i = 2; i <= (n); i++) {
if (n % i === 0) return false;
}
return true;
}

const primes = [];
for (let i = 2; i <= limit; i++) {
if (isPrime(i)) primes.push(i);
}

console.log(primes.join(","));
}
