Go Development

Apply idiomatic Go principles from Effective Go, the Go Code Review Comments wiki, and Go Proverbs to all code in this session.

Core Principles (Go Proverbs)

• Don't communicate by sharing memory; share memory by communicating
• The bigger the interface, the weaker the abstraction
• Make the zero value useful
• Errors are values — handle them, don't just check them
• A little copying is better than a little dependency
• Don't panic — use errors for normal control flow

Error Handling

Always return errors as the last value. Use early returns — no else after an if err != nil block.
