In GoLang, converting a byte slice to a string is as simple as using the string type conversion. To convert a string to a byte slice in Go, use the standard []byte conversion expression []byte(string). The The simplest approach is to just string(p), which will convert the []byte into a string - with the caveat that not all bytes are guaranteed to be valid UTF-8 characters (runes).
