How to compare two byte slices for case-insensitive equality in Go using the bytes package?

To compare two byte slices for case-insensitive equality in Go using the bytes package, you can make use of the bytes.EqualFold function. This function performs a case-insensitive byte-by-byte comparison between two byte slices and returns true if they have the same content, regardless of the case.

Here's an example code snippet demonstrating the usage of bytes.EqualFold:

package main

import (
	"bytes"
	"fmt"
)

func main() {
	// Sample byte slices
	slice1 := []byte("Hello")
	slice2 := []byte("hello")

	// Comparing byte slices for case-insensitive equality
	equal := bytes.EqualFold(slice1, slice2)

	// Output the result
	fmt.Println(equal) // Output: true
}

In the above example, bytes.EqualFold is used to compare two byte slices slice1 and slice2 for case-insensitive equality. Since the content of both slices is the same despite different case, it returns true.

Note: The bytes.EqualFold function is available starting from Go version 1.5. If you are using an older version, you can convert the byte slices to lowercase and then compare them using bytes.Equal.
