陳皓：如何寫(xiě)出無(wú)法維護(hù)的代碼

https://coolshell.cn/articles/4758.html

沒(méi)有尾探，導(dǎo)致箭頭式代碼

爭(zhēng)議：閱讀困難，編寫(xiě)省力（少return）

IDEA Alt+ Enter 可以自動(dòng)重構(gòu)，添加return

函數(shù)嵌套、對(duì)象嵌套 一層又一層

避免上級(jí)干擾，堅(jiān)持正確的設(shè)計(jì)

“在引起問(wèn)題的框架內(nèi)思考，將永遠(yuǎn)無(wú)法解決問(wèn)題?！?/p>

model - view - controller

MVC 的初衷

• 提高模塊復(fù)用程度
• 提高可讀性
• 提高可測(cè)試性

model - view - presenter

diff MVP MVC區(qū)別：

The Controller works as the entry point, but in MVP, the entry point is View.

業(yè)務(wù)快速發(fā)展，代碼快速累積

重構(gòu)不算績(jī)效，沒(méi)有動(dòng)力

單項(xiàng)依賴(lài)，重構(gòu)成本低

基于MVP，增加了 “統(tǒng)籌層”

1~2個(gè) if-else block

use case 單元測(cè)試

MVC適用Java后端服務(wù)

Android開(kāi)發(fā)種，MVC已經(jīng)不流行
