# 🏅 Day 19 - 函式觀念四

依照下方程式碼練習，並回答問題。

### 函式的 return 觀念

可參考課程影音「函式 function - return 寫法、return 可以有多個」章節

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
---
1. 下方敘述何者正確
(1) 一個函式中不能有多個 return
(2) return 的值可以賦予到變數上，像是下方程式碼中變數 `midNum` 最後的值會變為 `2`

    let midNum = 0;
    function calcMidNum(num1,num2) {
      return (num1 + num2) / 2;
    }
    midNum = calcMidNum(1,3);

2. 觀看下方程式碼，選出正確敘述

    let awardMoney = 0
    function getAward(score) {
      if(score >= 90) {
        console.log("贏得獎金 100 元");
        return 100;
      } else if(score >= 60) {
        console.log("贏得獎金 50 元");
        return 50;
      } else {
        console.log("再接再厲！");
      }
      console.log("比賽結束！");
    }
    awardMoney = getAward(85);

選項：
(1) 最後會印出 2 個字串
(2) `awardMoney` 最後的值為 85
(3) `awardMoney` 最後的值為 50
