Ever looked at your code and thought, “There must be a better way to organize this.” That’s where design patterns come in.
In this post, we will explore what design patterns are, why they matter, and how they are categorized.
What Are Design Patterns?
Design patterns are proven, reusable solutions to common software design problems. Think of them like templates or blueprints—not code that you copy and paste, but rather ideas and structures that guide you in solving recurring problems in a clean, efficient, and maintainable way.
The Three Main Categories of Design Patterns:
Design patterns generally fall into three broad categories, each addressing a different kind of software design problem:
1. Creational Patterns
These deal with object creation mechanisms, trying to create objects in a manner that is suitable to the situation. They help make a system independent of how its objects are created, composed, and represented.
Examples: Singleton, Factory Method, Builder, Abstract Factory, Prototype
2. Structural Patterns
These focus on how classes and objects are composed to form larger structures. They help ensure that if one part of a system changes, the entire system doesn't need to do the same.
Examples: Adapter, Composite, Proxy, Decorator, Bridge, Facade
3. Behavioral Patterns
These are concerned with communication between objects, focusing on the responsibilities and the flow of control in a program.
Examples: Observer, Strategy, Command, State, Iterator, Mediator
What's Coming Next?
In the upcoming posts, I’ll break down each design pattern—complete with real-world analogies, use cases, pros & cons, and practical examples in code.
Whether you’re a beginner developer or someone brushing up on architectural skills, this series will help you think more clearly about software design.
