## What it is
A collection of example implementations of all classic GoF design patterns in TypeScript, Java, and PHP, part of the Refactoring.Guru educational project. Each pattern includes a conceptual example showing internal structure and a real-world example demonstrating practical usage in web applications.

## Use cases
- learn design patterns with runnable code examples
- see how the singleton pattern is implemented in TypeScript
- study real-world examples of the builder pattern
- refresh my knowledge of GoF patterns before an interview
- find reference implementations of adapter and decorator patterns
- teach design patterns to a team with commented examples

## When to choose
- you want clear, well-commented examples of classic design patterns in TypeScript, Java, or PHP
- you are learning or teaching object-oriented design and want both conceptual and real-world code
- you want to accompany the free Refactoring.Guru pattern catalog with runnable code

## When to avoid
- you need a production-ready pattern library or framework to import into your project
- you need code you can redistribute or modify commercially, since the content is CC BY-NC-ND licensed
- you work in a language other than TypeScript, Java, or PHP
