Introduction to SOLID Principles

SOLID is an acronym that represents five key object-oriented design principles aimed at writing clean, scalable, and maintainable software. Introduced by Robert C. Martin (Uncle Bob), these principles help developers avoid code smells, reduce tight coupling, and enhance the flexibility of their applications.

Whether you're designing a small module or architecting a complex system, applying the SOLID principles ensures your code is easier to understand, test, and extend. Here's a quick overview of what each letter stands for:

• S – Single Responsibility Principle

• O – Open/Closed Principle

• L – Liskov Substitution Principle

• I – Interface Segregation Principle

• D – Dependency Inversion Principle
