How to create an empty byte slice in Go using the bytes package?

To create an empty byte slice in Go using the bytes package, you can use the New() function. Here is an example:

package main

import (
	"bytes"
	"fmt"
)

func main() {
	// Create an empty byte slice using the bytes package
	b := bytes.NewBuffer(nil)

	fmt.Println(b.Bytes())
	fmt.Println(len(b.Bytes()))
}

In this example, we are using the New() function from the bytes package to create an empty byte slice. The function takes a byte slice as input, so passing nil will create an empty byte slice.

The b variable can then be used to perform operations on the byte slice. In this example, we are printing the byte slice using b.Bytes() and its length using len(b.Bytes()). Both of these will output [] (empty byte slice) and 0 respectively.
