Purpose

Design patterns are reusable solutions to common problems in software design.
This repository showcases how classic patterns are best implemented in Go — emphasizing simplicity, clarity, and idiomatic Go style.

Patterns help with:

• Clean and maintainable architecture
• Scalability and extensibility
• Shared design vocabulary among developers
