Idiomatic Go error handling favors returning errors as values rather than using exceptions. You should check errors immediately, wrap them with context using fmt.Errorf, and design errors as types to build robust and maintainable applications.

Idiomatic Go concurrency uses goroutines and channels to share memory by communicating. Follow standard programming patterns by favoring simplicity, avoiding shared state, and properly coordinating goroutines to build efficient concurrent applications.

Structuring Go packages effectively requires favoring simplicity and designing small, focused interfaces. Apply standard Go conventions to package structure to ensure your application remains maintainable and robust as it scales.

Optimize Go performance by pre-allocating slices to avoid dynamic memory allocation and using sync.Pool to reuse objects. These programming patterns significantly reduce garbage collection overhead and improve application efficiency.

Common Go anti-patterns include overcomplicating interface design, ignoring error checks, and misusing concurrency primitives. Avoid these by favoring simplicity, making zero values useful, and following standard idiomatic conventions.

Using recommended Go linter configurations helps enforce idiomatic code and best practices. Linters integrate with standard Go tooling to automatically detect anti-patterns, ensuring your application remains robust and maintainable.
