函式觀念四
---
建議同學都將以下程式碼貼入 CodePen 執行、觀察結果。

### 函式的 return 觀念 ([參考章節1](https://courses.hexschool.com/courses/20201113/lectures/34094713)、[參考章節2](https://courses.hexschool.com/courses/20201113/lectures/34094716))
１. 函式可以用 return 回傳一個值，並可以將該值賦予給其他變數。

function calcTotalScore(chineseScore, englishScore){
    let total = chineseScore + englishScore;
    return total;
}

// 將 calcTotalScore 的回傳值賦值給 markScore。
let markScore = calcTotalScore(60, 50);
console.log(markScore);

2. return 會中斷函式執行，可以有多個 return、搭配 if else 做使用。

function calcTotalScore(chineseScore, englishScore){
    let total = chineseScore + englishScore;
    
    // 在此因為 total > 100，所以在第一個 if 函式就中斷了
    if(total > 100){
        return `總分 ${total}，做的好啊 mark`;
    }else{
    	return `總分 ${total}，考得不是很好 mark`;
    }

    // 以下的 return 都不會執行
    return chineseScore;
    return englishScore;
}

let markScore = calcTotalScore(60, 50);
console.log(markScore);

問題
