What is the difference between error handling and exceptions in Go?

In Go, error handling is done explicitly using return values, while exceptions are not used as in other languages.

Can you give me an example of error handling in Go?

Sure! In Go, a function can return an error as a second return value. You check it like this:

result, err := someFunction()
if err != nil {
    // handle the error
}

Why does Go prefer this method over exceptions?

Go's approach promotes clarity and simplicity, making it easier to understand where errors can occur and how they are handled.

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.
