The random string function always return the same value

[nam-truong-le]

The function returns different values in sequential calls but the initial value is always the same:

// You can edit this code!
// Click here and start typing.
package main

import (
    "fmt"

    "github.com/samber/lo"
)

func main() {
    result1 := lo.RandomString(5, lo.LettersCharset)
    result2 := lo.RandomString(5, lo.LettersCharset)

    fmt.Printf("%v %v", result1, result2)
}

Do I need to provide any seed value?

Based on this reference to this playground, it doesn't seem so.

The first run generated pubyc and the second run generated CIhQr.

Since go 1.20, rand.Seed(...) is executed automatically at program startup.
