FWIW If the router was in C or Rust or .net (which has a Jit for their regex engine) I would still tell you Regex is the wrong tool for splitting a URL on '/'. How many people have to tell you facts for you to believe them? Forget your pointless anti-go bias. A regex, while perfectly good for certain types of pattern matching makes no sense here.

I often have taught the same lesson to my junior colleagues who use regex in Python or C++ code where splitting the string would be simpler, more maintainable, and faster.

Because a few people on HN is the consensus ? give me a break. You have your opinion, I've got mine, whatever you think you are you're in no way an authority on the matter. There are many ways to implement an http router, there are also many ways to implement regular expressions. A bad implementation isn't saved by deeming the use of regexp "wrong tool for the job".

What make no sense is your petty comment.

Pointing out facts is "anti-go bias". OK , how about you stopping drinking the "pro-go koolaid" ?

I think you're a bit delusional, I don't even write go (hence there literally being no koolaid for me to drink), but you're free to continue disagreeing, and continuing to be wrong :)
