Know when to use inheritance and when to use composition. Inheritance is useful for “is-a” relationships, while composition is more suitable for “has-a” relationships.

Refrain from creating classes that do everything or have too many responsibilities. Split such classes into smaller, more focused ones.

As your codebase evolves, refactor it regularly to keep it clean, maintainable, and flexible. Refactoring improves code readability, reduces complexity, and eliminates code smells.

Write tests before writing the actual code. This helps in designing classes with clear interfaces and ensures that your code behaves as expected.

Use meaningful names for classes, methods, and variables. Write clear and concise documentation and comments to make your code more understandable.

Familiarize yourself with common design patterns like Factory, Singleton, Observer, Strategy, etc. These patterns provide proven solutions to recurring design problems.

Write classes and methods in a way that they can be easily reused in different parts of your application or even in different projects.

Make class attributes private (or protected) and provide public methods (getters/setters) to access and modify them. This protects the integrity of the data and allows for controlled access.

Each class should have a single, well-defined purpose. Avoid creating classes that try to do too much.

Use composition to build complex objects from simpler ones rather than relying heavily on class inheritance. This promotes flexibility and code reuse.
