Learn fundamental error handling in Go through this 12-minute tutorial that demonstrates how Go uses ordinary values instead of exceptions for error management. Discover how to create errors using the standard library's errors.New function, implement the common Go pattern of returning both results and errors from functions, and check for problems by comparing error values with nil. Master the conceptual approach where errors are normal values that keep control flow explicit and simple, with functions returning default values alongside errors when something goes wrong, and real results with nil when operations succeed. Explore how this error handling pattern appears throughout Go's standard library and forms the foundation for more advanced techniques like error wrapping and custom error types. Practice implementing early returns when errors occur to maintain clear, readable code that encourages simple control flow over exception-based approaches.
