Description

In Go, it is recommended to use fmt.Errorf() instead of errors.New(fmt.Sprintf()) for creating error values. The fmt.Errorf() function provides a more expressive and convenient way to generate error values by allowing the formatting of error messages.

Compliant Code Examples

package main

import (
