Generating UUIDs in Go

In Go, you can use the uuid package to generate universally unique identifiers (UUIDs). Here’s an example of how to generate a random UUID:

package main

import (
	"fmt"
	uuid "github.com/satori/go.uuid"
)

func main() {
	// Generate a random UUID
	u1 := uuid.NewV4()
	fmt.Printf("UUIDv4: %s\n", u1)
}

This will output a string representation of a UUID in the form of xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, where x is a hexadecimal digit.

If you need to generate a UUID based on a specific input, you can use the NewV5 function and provide a namespace and a name as arguments. For example:

u2 := uuid.NewV5(uuid.NamespaceURL, []byte("example.com"))
fmt.Printf("UUIDv5: %s\n", u2)

This will generate a UUID based on the namespace uuid.NamespaceURL and the name "example.com".
