+ Rails Bridge 自主練習
+ BOARD GAME
19:30 開始
前情提要
1 - INTENTION REVEALING METHOD
• code 讀懂以後加上註解
• 註解變 method
2 - SPECIAL CASE OBJECTS
• 從源頭動⼿手腳，解決 nil 造成的⿇麻煩
3 - REPLACE METHOD WITH METHOD OBJECT
• 把肥⼤大 method 變成 class
• 在 class 內 refactoring
4 - SERVICE OBJECT
• ⺫⽬目標：
• 把 subscribe 相關功能抽成 service object
• 讓原本的 subscribe、unsubscribe 變成只負責去叫 service object (Delegate)
