How can I effectively handle errors in Go?

In Go, you can handle errors by returning an error value from functions. It's common to check if the error is nil before proceeding.

Can you show me an example of error handling in a function?

Sure! Here's a simple example:

func divide(a, b float64) (float64, error) {
    if b == 0 {
        return 0, fmt.Errorf("cannot divide by zero")
    }
    return a / b, nil
}

What about logging errors? How should I do that?

You can use the log package in Go. For example:

if err != nil {
    log.Println(err)
}
``` This will log the error message.

Are there any best practices for error handling in Go?

Yes, some best practices include wrapping errors with context, using custom error types, and always checking for errors.
