The go language passes functions as parameters

This is a creation in Article, where the information may have evolved or changed.

The Go language function is passed as a parameter, and now I feel almost the same as C + +. It's very flexible.

Import "FMT" import "Time" Func goFunc1 (f func ()) {        go f ()}func GoFunc2 (f func (interface{}), I interface{}) {        go f ( i)}func gofunc (f interface{}, args ... interface{}) {        If Len (args) > 1 {                 go f. (Func (... interface{})) (args)        } else If Len (args) = = 1 {                 go f. (Func (interface{})) (Args[0])        } else {                go f. (func ()) ()        }   }func F1 () {        fmt. Println ("F1 done")}func F2 (i interface{}) {        fmt. Println ("F2 done", i)}func f3 (Args ... interface{}) {fmt.        Println ("F3 done", args)}func main () {        goFunc1 (F1)        GoFunc2 (F2, +) Gofunc (F1                )        gofunc (F2, "xxxx" )        Gofunc (F3, "Hello", "World", 1, 3.14) time        . Sleep (5 * time. Second)}

F1 done
F2 done 100
F1 done
F2 done xxxx
F3 done [[Hello World 1 3.14]]
