    # 第三十六關 - ES6 起步走 - Template String 樣板字串 明明小杰都已經完成任務,照理來說應該幫他加薪,但禿頭俠卻說公司擋掉了他的加薪申請。 原因是技術主管認為他寫的 Code 太菜了,他們認為現在已經是 2020 年,JavaScript 的寫法已經晉升到 ES6、7,所以請小杰先好好升級自己的程式碼,才可以跟公司團隊一起開發。 # 問題 禿頭俠說,他看了小杰[第 20 關](https://hackmd.io/@YmcMgo-NSKOqgTGAjl_5tg/Sk-_oGL2U/https%3A%2F%2Fhackmd.io%2F3cuxdNsWS6qLNh6KqVYVkw%3Fview)程式碼,發現他的字串相加語法可以用 [Template String 樣板字串](https://ithelp.ithome.com.tw/articles/10192949)來改寫。 例如原本寫法是 ``` var people = [ { name: '小明', friends: 2 }, { name: '阿姨', friends: 999 }, { name: '杰倫', friends: 0 } ] let originString = '我叫做 ' + people[0].name; // 過去的寫法 let originUl = '<ul>\ <li>我叫做 ' + people[0].name + '</li>\ <li>我叫做 ' + people[1].name + '</li>\ <li>我叫做 ' + people[2].name + '</li>\ </ul>'; // 多行的寫法 ``` 用 ES6 寫法可以改為 ``` let ul = ` <ul> <li>我叫做 ${people[0].name}</li> <li>我叫做 ${people[1].name}</li> <li>我叫做 ${people[2].name}</li> </ul> ` ``` 請改寫您[第 20 關](https://hackmd.io/@YmcMgo-NSKOqgTGAjl_5tg/Sk-_oGL2U/https%3A%2F%2Fhackmd.io%2F3cuxdNsWS6qLNh6KqVYVkw%3Fview)的字串相加邏輯,以符合 ES6 寫法 ![](https://i.imgur.com/0yq8k8n.png) ## 如果你已經早就會 ES6 字串處理,請觀看以下文章,挑選一個你不會的技術觀念,並分享你學到了什麼 * [邁向 JavaScript 勇者之路](https://ithelp.ithome.com.tw/users/20083608/ironman/1354) * [重新認識 JavaScript](https://ithelp.ithome.com.tw/users/20065504/ironman/1259) * [ES6 入門手冊(較於艱深)](https://es6.ruanyifeng.com/) ## fetch 除了使用 axios套件來抓取遠端 JSON資料,還有一個原生語法 - 參考 邁向 JavaScript 勇者之路 ## 以下分享您的心得文章 * [JS 學徒特訓班 36 ES6 起步走 - Fetch 練習筆記](https://hackmd.io/@5-dKGDt1RDCoDDAr4DP-qg/B1Lxu-3lP)
