Don’t Repeat Yourself (DRY) principle

The DRY (Don't Repeat Yourself) principle is a software development best practice that emphasizes the importance of reducing redundancy and improving maintainability by avoiding repetition of code or logic.

DRY principle can be applied in several ways:

Code reuse: Instead of repeating the same code in multiple places, create reusable components such as classes, methods, or functions that can be called from different parts of the code.

Inheritance: Inheritance allows you to reuse code from existing classes to create new classes. This reduces duplication and makes the code easier to maintain.

Polymorphism: Polymorphism allows you to write code that can work with objects of different classes, reducing the need to write separate code for each class.

Design patterns: Design patterns are reusable solutions to common software design problems. By using design patterns, you can avoid reinventing the wheel and write more maintainable code.

Overall, the DRY principle is a fundamental principle of software development that can help improve code quality, reduce bugs, and make code easier to maintain over time.
