The bytes.Clone() is a new function added in Go 1.20 that “returns a copy of a byte slice with a new backing array.” It is similar to copy() or make() functions but more convenient.
Syntax
func Clone(b []byte) []byte
Parameters
byte: It takes a byte slice as a parameter.
Return value
It returns a copy of b[:len(b).
Example
package main
import (
"bytes"
"fmt"
)
func main() {
// Create a byte slice
b := []byte("Hello, world!")
fmt.Println("Original:", string(b))
// Clone the byte slice
c := bytes.Clone(b)
fmt.Println("Clone:", string(c))
// Modify the original byte slice
b[0] = 'h'
fmt.Println("Modified original:", string(b))
// The clone is not affected
fmt.Println("Clone:", string(c))
}Output
Original: Hello, world!
Clone: Hello, world!
Modified original: hello, world!
Clone: Hello, world!That’s it!
