    # Day 28 - Review code 因團隊制宜。 假設桌球王成立團隊,將會有以下`Pricinple`、`SOP`、`CheckList`、`Take away`。 ## Principle 以Priority由上而下: 0. 確認邏輯**無誤** 1. 確認如何操作APP 2. **了解**背後運作邏輯 3. 減少重複 : 重複使用的邏輯包成function : 不用改一個地方,四處都要改 4. 增加可讀 : 命名 : 結構 : 刪除沒有使用的 ## SOP & Document 可執行 round N ,N大於等於1。 round N ,依複雜性,及當round吸收程度來決定N為多少。 每 round 有其`主題`,比如說某次Release,加了哪些Feature、操作步驟/流程、前端架構,後端API、網路連線(關聯系統)、Config.等等。 最後的吸收理解可以邊看文件邊Trace Code,整個走一次確認是否大略知道重點,以便未來查案或加值。 ## Check List - [ ] 了解user怎麼操作,通常哪些使用頻繁 - [ ] 前後端交握,哪些前端處理,傳遞給後端,後端Status code 回傳 - [ ] 上下游(關聯) 系統,如何溝通,正常異常判別 - [ ] log 識別 以及 量的控制 ## Take away Review Code 的同時其實可以看到更多或是更好的寫法或架構, 如果可以看出原開發沒有發現的邏輯問題,就能即時在上線前排除, 也能想想看有沒機會在不改變輸出的情況,改出易於維運的Code。 其實是 reviewer 與 commiter(developer) 之間的切磋成長! ## 相關參考 - [Code Review 怎麼做](https://tw.alphacamp.co/blog/code-review)
