# 🏅 Day 17 - 函式觀念二

依照下方程式碼練習，並回答問題。

### 函式裡面仍可以執行函式

[課程影音連結](https://courses.hexschool.com/courses/202011131/lectures/42391124)

function dailyAction() {
  cleanHead();
  console.log("出門");
  console.log("回家");
  cleanHead();
} 
function cleanHead() {
  console.log("刷牙");
  console.log("洗臉");
} 
dailyAction();

> 函式內部可以呼叫其他函式，
> 可以重複利用程式碼、簡潔版面。

問題
---
1. 觀看以下程式碼，利用函式觀念二，嘗試優化 `todayTask()` 函式

function todayTask() {
  console.log("觀看課程");
  console.log("製作筆記");
  console.log("每日任務");
  console.log("觀看課程");
  console.log("製作筆記");
  console.log("主線任務");
  console.log("觀看課程");
  console.log("製作筆記");
}
function watchAndNote() {
  console.log("觀看課程");
  console.log("製作筆記");
}

2. 觀看以下程式碼，最後會印出什麼

function printNumbers() {
  printOne();
  console.log("11");
  printOne();
}
function printOne() {
  console.log("1");
}
printOne();

## 回報流程

將答案寫在 CodePen 並複製 CodePen 連結貼至底下回報就算完成了喔!
解答位置請參考下圖（需打開程式碼的部分觀看）


<!-- 解答：

1.

function todayTask() {
  watchAndNote();
  console.log("每日任務");
  watchAndNote();
  console.log("主線任務");
  watchAndNote();
}
function watchAndNote() {
  console.log("觀看課程");
  console.log("製作筆記");
}

2. 1
（原因：printNumbers() 沒有呼叫！）
