實驗羊 2019-3-9 12:05:48 所以啲人問

你最多係用邊個 Design Pattern sounds like an on9 question

青花瓷 2019-3-9 12:16:43 用我上面句野答

:^(

青花瓷 2019-3-9 12:17:44 and no two patterns are the same

實驗羊 2019-3-9 12:42:27 Yes ar

Actually I use the most consistent is Singleton

i-vtec找J/屎眼數 2019-3-9 13:09:27 Singleton

手一黏便緊(UTC+9 2019-3-9 14:10:39 決定左有咩feature之後先決定用咩design pattern囉

:^(

Trinidad 2019-3-9 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

實驗羊 2019-3-9 15:00:00 唔執你手尾

:^(

實驗羊 2019-3-9 15:00:57 So you will think about which design pattern to use before actually writing?

實驗羊 2019-3-9 15:01:53 Yes ar
But even when I refractor I only follow DRY code and Single source of truth

實驗羊 2019-3-9 15:02:08 What’s wrong

Trinidad 2019-3-9 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

Trinidad 2019-3-9 16:00:31 一個大class搞哂所有野

實驗羊 2019-3-9 16:07:25 100K 月薪 and 100K lines of code

Trinidad 2019-3-9 16:08:58 singleton好多時係為寫而寫

:^(

實驗羊 2019-3-9 16:10:44 MVC need single data model wor

Trinidad 2019-3-9 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

實驗羊 2019-3-9 16:13:37 But every app I developed always have 1 Singleton

Only 1 tho

Trinidad 2019-3-9 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

手一黏便緊(UTC+9 2019-3-9 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

手一黏便緊(UTC+9 2019-3-9 16:29:03 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...

Trinidad 2019-3-9 16:29:11 你有backend架嘛
