Explore the foundational work of the Gang of Four in design patterns, their impact on object-oriented design, and their lasting relevance in modern software development.
Explore the three main categories of design patterns in Java: Creational, Structural, and Behavioral. Understand their roles, examples, and how they enhance software design.
Explore how the State pattern, a behavioral design pattern, enables objects to change behavior dynamically by altering their internal states. Learn about its components, advantages, and practical applications in software architecture.
Explore the State Pattern through the analogy of a traffic light system, illustrating how state-specific behavior is managed and transitions are controlled.
Explore the Visitor Pattern, a behavioral design pattern that separates algorithms from object structures, allowing for scalable and maintainable code.
Explore the role of the Context class in the Strategy Pattern, its interaction with strategies, and how to select and manage strategies effectively in Java applications.
Explore the Strategy pattern in software design, its purpose, benefits, and implementation in JavaScript and TypeScript. Learn how to define interchangeable algorithms and apply them effectively in your projects.
Explore the Strategy Pattern in JavaScript, learn how to implement it using functions or classes, and understand best practices for dynamic strategy selection.
Learn how to implement the Command Pattern in JavaScript with practical examples, including a remote control simulator. Explore best practices, undo functionality, and testing strategies.
Explore the Command Pattern through a practical example of a universal remote control system in Java, illustrating the decoupling of commands from device implementations.
Explore the Chain of Responsibility pattern in Java, a powerful design pattern for decoupling senders and receivers by passing requests along a chain of handlers.
Explore the Chain of Responsibility Pattern in TypeScript with type-safe implementations, asynchronous handling, and best practices for server applications.
Explore the Mediator Pattern in JavaScript and TypeScript, focusing on reducing coupling among interacting objects, improving maintainability, and enhancing flexibility.
Explore the implementation of the Mediator Pattern in JavaScript, focusing on communication management between Colleague objects, practical applications, best practices, and strategies for scalability and performance.
Explore the Command Pattern in Python with practical examples. Learn to encapsulate requests as objects and implement undo/redo functionality in a text editor.
Explore the Strategy Pattern in Python using function objects to create flexible, reusable algorithms. Learn how to implement, optimize, and apply this pattern in real-world scenarios.
Discover how Python's generator functions and iterator protocol make implementing the Iterator pattern natural and efficient. Learn through comprehensive examples and best practices.
Explore the Iterator pattern, a powerful design pattern that allows sequential access to elements of a collection without exposing its underlying structure. Learn how it promotes encapsulation and flexibility in software design.
Explore the Strategy Pattern in depth, understand its implementation in JavaScript and TypeScript, and learn how it fosters flexibility and the Open/Closed Principle in software design.
