Design-patterns

In this post, we delve into the Builder design pattern. This pattern helps manage the construction of complex objects by separating their construction from their representation. By offering a step-by-step approach to object creation, the Builder pattern enhances readability and maintainability of code. The article also includes the simplified javascript approach and comparison to traditional methods.

The Command pattern is a behavioral design pattern that encapsulates a request or operation as an object. It allows decoupling the sender of a request from the receiver, enabling greater flexibility and extensibility in a system. By encapsulating commands as objects, the Command pattern enables parameterizing clients with different requests, logging requests, and implementing undo/redo functionality.

The Dependency Inversion Principle (DIP) is a fundamental design principle in software development. It promotes decoupling between modules by depending on abstractions rather than concrete implementations. By relying on interfaces and abstract classes, the DIP allows for flexibility, easier testing, and improved maintainability.

An introduction to the concept of design patterns. They offer common solutions to recurring software design problems and promote clean, efficient code. Understanding when and how to use them appropriately is crucial to avoid unnecessary complexity.

The Facade pattern is a structural design pattern that provides a simplified interface to a complex subsystem or set of classes. It acts as a unified interface that encapsulates the underlying functionality and presents a simplified view to clients. By using the Facade pattern, clients can interact with a high-level interface without needing to understand the complexities of the underlying system.

Interface Segregation is a principle in software design that emphasizes the creation of specific and cohesive interfaces. It promotes the idea that clients should not be forced to depend on interfaces they do not use. By segregating interfaces into smaller, more focused units, we can achieve better encapsulation, reduce coupling, and enhance code maintainability.

The Liskov Substitution Principle (LSP) is a fundamental principle in object-oriented programming. It states that subclasses should be able to be used in place of their parent classes seamlessly. Adhering to LSP ensures that code remains robust, maintainable, and extensible, allowing for polymorphism and enabling the use of interfaces and abstract classes effectively.

This article provides a comprehensive exploration of the Null Object Pattern in programming. The technique helps enhance code by offering a default substitute for non-existent objects, improving readability, and maintainability. Practical examples and potential pitfalls of the pattern are also discussed.

The Open-Closed Principle (OCP) is a key principle in object-oriented programming that states software entities should be open for extension but closed for modification. It encourages designing modules that can be easily extended with new functionality without modifying existing code. By adhering to the OCP, we create software systems that are more flexible, maintainable, and resistant to changes.

The Single Responsibility Principle (SRP) states that a class or module should have only one reason to change. It promotes a clear and focused responsibility for each component, making code easier to understand, maintain, and extend. By adhering to SRP, developers can achieve higher cohesion and lower coupling, resulting in more robust and scalable software systems.

The Singleton design pattern ensures that a class has only one instance and provides a global point of access to it. It is useful in scenarios where there should be a single, shared instance of a class throughout the application. The Singleton pattern guarantees that multiple instances cannot be created, and it provides a centralized way to access the instance.
