Golang - How do you create a slice of functions with different signatures?

Question

How do you create a slice of functions with different signatures? I tried the code below but its feels hack-ish. Do we just bite the bullet and use a slice interface{}?

Answer 1

depends on what the different you need. upon your example, we could use variadic.

package main

import(
    "fmt"
    "strings"
)

func foo(ss ...string) string{
    return strings.Join(ss, " ")
}

func main(){
    fmt.Println(foo("one"))
    fmt.Println(foo("one", "two"))
    fmt.Println(foo("one", "two", "three"))
}
