What are some common Go error handling examples?

Can you give me some examples of error handling in Go?

Sure! In Go, error handling is typically done using the error type. For example, you can return an error from a function like this: func doSomething() error { return errors.New("an error occurred") }.

How do I check if an error occurred?

You can check if an error occurred by comparing the returned error to nil. For example: if err != nil { fmt.Println(err) }.

What about using defer with error handling?

Using defer is great for cleanup. You can defer a function that handles errors, ensuring it runs after the surrounding function completes.

Can you show me a complete example?

Absolutely! Here's a simple example:

package main
import (
	"errors"
	"fmt"
)

func doSomething() error {
	return errors.New("an error occurred")
}

func main() {
	if err := doSomething(); err != nil {
		fmt.Println(err)
	}
}
