How to convert a string to a slice of bytes ([]byte) in Go?

Hi everyone! I just started learning Go and ran into a problem. I need to write a string into a byte array, or more precisely — into a `[]byte` slice. I know that in Go strings are an immutable sequence of bytes in UTF-8 encoding, and a byte slice is a mutable structure. But I don't understand how to connect them. Here's what I tried: ```go package main import "fmt" func main() { var s string = "Hello, Go!" var b []byte // First attempt: just assign b = s // Error: cannot use s (type string) as type []byte in assignment // Second attempt: create a slice and copy b = make([]byte, len(s)) copy(b, s) // This worked, but I'm not sure if it's correct fmt.Println(b) } ``` Question: how to correctly and efficiently convert a string to a byte slice?
