What are the different ways to handle errors in Go?

Go provides several ways to handle errors, primarily using multiple return values and the `error` interface. Functions can return both a result and an error value. If an error occurs, the error value is returned; otherwise, the result is returned. `fmt.Errorf` is used to create error messages. The `error` interface allows you to define custom error types and handle them specifically. Panics are a last resort for unrecoverable errors. Additionally, using `errors.Is` and `errors.As` can simplify error checking and handling.
