題目
---
1. 請修正以下程式碼錯誤，並執行 console.log
2. 請嘗試說明以下程式碼錯誤的原因

let saySomething = '小姐一個人嗎 :D'
(function() {
  console.log(saySomething);
})

## 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. 應該更正為:
let saySomething = '小姐一個人嗎 :D'
;(function() {
console.log(saySomething);
})()

2.
a. 使用立即函式需要在結尾的部分加入一組 () 才會正確執行。
b. 由於題目的 JS 程式碼在運行時會被視為同一行，如下:

let saySomething = '小姐一個人嗎 :D'(function() {console.log(saySomething);})

如果要避免此錯誤就需要使用分號將其隔開。
