Explain how error handling is typically done in idiomatic Go code.
- Ignoring errors for simplicity.
- Returning errors as values.
- Using global error variables.
- Using try-catch blocks.
In idiomatic Go code, error handling is typically done by returning errors as values. Functions that can potentially encounter an error return a value of type error. This allows the calling code to check for errors explicitly by examining the returned error value and taking appropriate action, such as logging the error or returning it further up the call stack. This approach encourages explicit error handling and is a key feature of Go's error-handling philosophy.
