Create a Random String in Go

package main

import (
	"fmt"
	"math/rand"
	"time"
)

var r = rand.New(rand.NewSource(time.Now().UnixNano()))

func RandomString(strlen int) string {
	const chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
	result := make([]byte, strlen)
	for i := range result {
		result[i] = chars[r.Intn(len(chars))]
	}
	return string(result)
}

func main() {
	fmt.Println(RandomString(10))
}
