How would you use the errors package to create custom error types?
- Import the errors package and use its functions
- Use the errors.New() function to create a new error type
- Modify the built-in error type
- Use the custom_error package
In Go, you can create custom error types using the errors package by utilizing the errors.New() function. This function allows you to create a new error type with a custom error message. For example, you can create custom errors like MyError := errors.New("This is a custom error message"). This way, you can provide more specific and informative error messages when needed, making it easier to identify the root cause of issues during debugging. Modifying the built-in error type is not recommended because it can affect all error instances in your program, potentially leading to confusion and unexpected behavior.
