How does exception handling work in Go?

How does exception handling work in Go?

In Go, we don't have traditional exception handling like in other languages. Instead, we use multiple return values and the error type.

Can you give me an example of how to handle errors 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
}

In this function, if b is zero, we return an error.

What should I do if I encounter an error?

You can check the error returned by the function. If it's not nil, handle it accordingly, like logging or returning it up the call stack.

Are there any best practices for error handling in Go?

Yes! Some best practices include always checking for errors, using descriptive error messages, and wrapping errors for context.
