所以啲人問

你最多係用邊個 Design Pattern sounds like an on9 question
2019-03-09 12:16:43
用我上面句野答
2019-03-09 12:17:44
and no two patterns are the same
2019-03-09 12:42:27
Yes ar

Actually I use the most consistent is Singleton
2019-03-09 13:09:27
Singleton
2019-03-09 14:10:39
決定左有咩feature之後先決定用咩design pattern囉
2019-03-09 14:19:15
從來都唔用
鳩寫爛曲算
行到咪得囉

singelton又要factory
搞咁多做乜？
有野咪new出黎用吓囉

唔執你手尾
2019-03-09 15:00:57
So you will think about which design pattern to use before actually writing?
2019-03-09 15:01:53
Yes ar
But even when I refractor I only follow DRY code and Single source of truth
2019-03-09 15:02:08
What’s wrong
2019-03-09 15:59:50
真係咁寫架喎
普通application 根本寫到靚一靚同諗到乜就寫乜出黎係冇分別
除非玩big data同好講performance 架啫

一個大class搞哂所有野

singleton好多時係為寫而寫
2019-03-09 16:10:44
MVC need single data model wor
2019-03-09 16:12:48
同用唔用singleton 係兩樣野黎
我睇法係好多野用singleton 都係哂鳩氣
2019-03-09 16:13:37
But every app I developed always have 1 Singleton

Only 1 tho
2019-03-09 16:17:48
乜先
同埋你以前玩java就話冇得揀
你寫c#有static class
static class定singleton 都有排拗
2019-03-09 16:25:13
咪諗下寫下諗下寫下咁既feedback loop囉 唔係完全唔諗 亦唔係落左決定就永世唔改
2019-03-09 16:27:17

又唔完全係為寫而寫
如果有N個class 本身啲object reference chain係好精巧既
但係你要改 要跨幾層class 而你既上一手同事又唔知死左去邊
咁最簡單咪就係改某啲class做singleton
最好一定係了解成個設計意圖 然後fit入去個chain到
但係同上一手同事有不可跨越既時空距離 都唔係我可以控制到既事黎...
