What are some effective error handling patterns in Go?

In Go, common error handling patterns include returning errors, using the error type, and leveraging defer for cleanup.

Can you explain how to use the defer statement for error handling?

Certainly! The defer statement allows you to schedule a function call to be run after the function completes, which is useful for cleanup.

What is the difference between handling errors with if statements and using panic?

Using if statements allows for graceful error handling, while panic is used for unrecoverable errors, terminating the program.

Are there any best practices for error handling in Go?

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