Likely PHP's call_user_func_array() or Javascritpt's callback(jsonObject)

call_user_func_array.go

package main

import (
	"errors"
	"fmt"
	"reflect"
)

func main() {
	funcs := map[string]interface{}{"foo": foo, "bar": bar}
	Call(funcs, "foo")
	Call(funcs, "bar", 1, 2, 3)
}

// Call is magic func.
func Call(m map[string]interface{}, name string, params ...interface{}) (result []reflect.Value, err error) {
	f := reflect.ValueOf(m[name])
	if len(params) != f.Type().NumIn() {
		err = errors.New("The number of params is not adapted")
		return
	}
	in := make([]reflect.Value, len(params))
	for k, param := range params {
		in[k] = reflect.ValueOf(param)
	}
	result = f.Call(in)
	return
}

func foo() {
	fmt.Println("test")
}

func bar(a, b, c int) {
	fmt.Println(a, b, c)
}

result:

test
1 2 3
