How can I handle errors in Go?

What are some common error handling practices in Go?

In Go, common practices include using the error type, checking errors immediately after a function call, and using panic/recover for unexpected situations.

Can you show me an example of error handling in a Go 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 should I do if I encounter a panic?

You can use the recover function to handle panics. It allows you to regain control of the program and handle the error gracefully.

Are there any libraries that can help with error handling in Go?

Yes, libraries like pkg/errors and go-errors provide enhanced error handling capabilities, such as stack traces and error wrapping.
