Golang Patterns

A comprehensive reference for idiomatic Go development that covers the language's core philosophy and practical patterns. It emphasizes Go's fundamental principles like making zero values useful, accepting interfaces while returning structs, and proper error wrapping with context. The concurrency section is especially solid, covering worker pools, errgroup coordination, and goroutine leak prevention. What I appreciate most is how it consistently shows both good and bad examples, making the reasoning clear. The interface design guidance around defining interfaces at the point of use rather than with the implementation is spot on and often overlooked by developers coming from other languages.
