What is the difference between errors and exceptions in Go?

What is the difference between errors and exceptions in Go?

In Go, errors are values that can be returned by functions, while exceptions are not used. Go uses a simple error handling model.

Can you give me an example of how errors are handled in Go?

Sure! In Go, you typically return an error as the last return value from a function. For example:

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

What happens if I don't check for errors?

If you don't check for errors, your program may continue executing with invalid data, leading to unexpected behavior or crashes.

Are there any best practices for error handling in Go?

Yes! Always check for errors immediately after calling a function that returns an error, and handle them appropriately to ensure program stability.
