behavioral-patterns

What problem does it solve?

Designing robust object interactions and distributing responsibilities can quickly lead to tangled conditional logic and brittle code. Behavioral design patterns provide reusable templates to coordinate how objects communicate, respond to events, and transition state.

Core Features & Use Cases

• Catalog of patterns (Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method, Visitor) with practical TypeScript examples.
• Guidance on when to apply each pattern, typical pitfalls, and real-world scenarios such as undo/redo, event broadcasting, and runtime algorithm selection.
• Quick-start references and minimal viable examples to bootstrap learning and usage in projects.

Quick Start

Demonstrate a simple chain of responsibility in TypeScript to explain how handlers pass control along a chain.
