ServeMux or Switch?

Question

Intellectual property

Tell me how to do it right and so that it works quickly.
There is a MAP with 50 languages, their descriptions and data in each language.
Do separate functions for all 50 languages?
mux.HandleFunc("/", indexHandler)
mux.HandleFunc("/ru", ruHandler)
mux.HandleFunc("/de", deHandler)
mux.HandleFunc("/fr", deHandler)
Or only one function in it handle all languages ​​with Switch
mux.HandleFunc("/", indexHandler)
func indexHandler(w http.ResponseWriter, r *http.Request) {
switch r.URL.Path{
//Search for language in map
case locales[r.URL .Path]:
fmt.Fprintf(w, "%s\n", r.URL) //Language found in map
default:
w.WriteHeader(http.StatusNotFound) // 404
fmt.Fprintf(w, "no such page: %s\n", r.URL)
}
}

Answer 1

you can use modified characters to the point of confusion, if you can prove in court that they were invented by you and just look like StarCraft ones, use plots / exact setting, etc. it's forbidden, it's like making a movie based on a book without the writer's permission

Answer 2

How convenient.
It is unlikely that you will distinguish those nanoseconds of difference in speed even when thousands of people come to your site at the same time.

Answer 3

If there is only one page, then it doesn't matter. If there are a lot of pages in each language, then it's probably better to use something like Gorilla mux with template/regex support.
