The DRY principle

The DRY principle (Don't Repeat Yourself) is a software development principle that advocates for avoiding repetition of code or logic in a program. It encourages developers to write code that is modular, reusable, and easy to maintain.

The DRY principle suggests that if a piece of information or code needs to be shared in multiple places, it should be defined in a single location, preferably in a central location. This helps to ensure that the code is consistent and reduces the chances of introducing bugs or errors due to inconsistencies.

By following the DRY principle, developers can write code that is more concise, easier to read, and easier to maintain over time. It is a fundamental principle of software engineering that is applicable to all programming languages and paradigms.
