Snippet
Error Handling Pattern
Instead of using exceptions, Go uses explicit error checking. Functions return an 'error' type as their last return value, which should be checked immediately.

result, err := doSomething()if err != nil {fmt.Println("Error occurred:", err)return}fmt.Println("Success:", result)
Breakdown
1
if err != nil
Checks if the returned error is not 'nil' (meaning an error occurred).
2
return
Exits the function early if an error is detected.
