唉 兩日無追，又爆左，無開

Lm 完回去低端區。。

點解大陸人咁鐘意golang
其實nodejs python ruby java 都做到backend/api
performance我相信唔會差好撚多
除非你話真係會1m + request per second
咁可能你咁玩真係勁D

唔係想讚golang
但你舉呢4個例子 頭3個就interpreted
Java compiled但就jvm
你真係覺得performance 唔會差好多？

隨便網上搵

我意思寫既時間
用golang 你知啦 有D撚屌鐘意唔用framework
好撚難睇

點解無咩人講C# .net framework
明明techempower ranking 都排第8
https://www.techempower.com/benchmarks/#section=data-r20&hw=ph&test=composite
performance 唔差
又有microsoft support

香港好似唔多人寫
利申 份工寫.net同angular
好似兩樣都冷門

想回應你關於framework嘅睇法
golang認為呢個係用家嘅責任去maintain readability之類嘅嘢
而有一班golang developer係有意識地唔用framework
通常都係java或者其他oop over-engineering嘅受害者
無framework唔代表無design pattern
千祈唔好一竹竿打沉一船人

https://talks.golang.org/2012/splash.article

The goals of the Go project were to eliminate the slowness and clumsiness of software development at Google, and thereby to make the process more productive and scalable. The language was designed by and for people who write—and read and debug and maintain—large software systems.

Go's purpose is therefore not to do research into programming language design; it is to improve the working environment for its designers and their coworkers. Go is more about software engineering than programming language research. Or to rephrase, it is about language design in the service of software engineering.

你最尾個句咪已經講咗個原因

之前搵到一個叫
buffalo
似rails
咁就睇落唔錯

現實係你唔需要咁low latency做咁大量計算
寫得快好過program run 得快
至於你話 scalable
呢家野係講係個system design 講你有幾多resources幾多replica 多過講你揀邊隻Lang
連登用php 味一樣scale 到

幾時有工請呀

寫得快好過program run 得快
好同意
所以我咪話其實nodejs python ruby java 都一樣得
你要寫golang唔係問題
但你唔用framework 個下就好難睇 你寫得亂 咪難main囉
而家D cloud咁勁 又container 又kubenetes 又load balancer 又可以serverless
大把野setup 加大CPU 加大memory 加大storage 大把方法可以搞得快D
真係好過整D冷門野

系樓上個傻晒系度嘈嘈嘈
系牙go 好能把炮，令你慳到幾百蚊cloud resources 錢牙，go 好能勁
然後為左寫go 就請人又麻煩，寫得又慢，人工蝕番幾十倍
