1. Single Responsibility Principle (SRP) A class should have only one reason to change. This principle promotes a focused approach where each class is responsible for a single task or functionality, reducing the chances of errors when making changes and enhancing maintainability. 2. Open/Closed Principle (OCP) Software entities should be open for extension but closed for modification. This means that you should be able to add new features or functionalities to your code without altering existing structures. This principle ensures that modifications don’t inadvertently introduce bugs into stable code. 3. Liskov Substitution Principle (LSP) Subtypes must be substitutable for their base types without affecting the correctness of the program. This principle ensures that derived classes extend base classes without changing their behavior, preserving the reliability of the code when using polymorphism. 4. Interface Segregation Principle (ISP) Clients should not be forced to depend on methods they do not use. By splitting large interfaces into smaller, more specific ones, you reduce the burden on classes and ensure they only implement relevant functionalities. This keeps your design modular and easier to refactor. 5. Dependency Inversion Principle (DIP) High-level modules should not depend on low-level modules; both should depend on abstractions. This principle emphasizes decoupling, allowing systems to be more flexible and less dependent on specific implementations, facilitating easier changes and scaling. Following the SOLID principles leads to robust and adaptable code that is easier to understand, extend, and test. These principles form the foundation of clean architecture and are crucial for professional software development. Which SOLID principle do you find most impactful in your coding journey? 🚀
