In the example, we write strings to the bytes buffer with WriteString and then convert the bytes into a final string with String function. $ go run main.go an old falcon Go strings.JoinThe strings.Join function joins string elements of a slice/array into one string. The separator string ...

package main import ( "fmt" "strings" ) func main() { s := []string{"There", "are", "two", "owls", "on", "the", "tree", "\n"} fmt.Printf(strings.Join(s, " ")) } In the code example, we form a message by joining multiple words. The words are joined with a single...
