What are some effective error handling strategies in Go?

What are some effective error handling strategies in Go?

In Go, effective error handling can be achieved using multiple strategies such as returning errors, using the error type, and leveraging panic/recover.

Can you explain how to use the error type in Go?

Sure! In Go, functions that can fail typically return an error as the last return value. You can check if the error is nil to determine if the operation was successful.

What is the difference between panic and recover?

Panic is used to indicate a serious error that should stop the normal execution of a program, while recover allows you to regain control of a panicking goroutine.

Are there best practices for error handling in Go?

Yes, some best practices include always checking for errors, wrapping errors for context, and using custom error types for better error handling.
