package bytes
Join concatenates the elements of input slice to create a new byte slice. A separator is placed between elements in the resulting slice.
Golang bytes.Join() function usage example
package main
import (
"bytes"
"fmt"
)
func main() {
a := []byte("Hello")
b := []byte(" World!")
c := [][]byte{a, b}
d := []byte{}
d = bytes.Join(c, []byte(", "))
fmt.Println(string(d))
e := []byte{}
e = bytes.Join(c, []byte("--"))
fmt.Println(string(e))
}
Output :
Hello, World!
Hello-- World!
