"Don't Repeat Yourself" (DRY) is a fundamental principle in software development and programming aimed at reducing the repetition of code patterns and ensuring that every piece of knowledge, logic, or data is represented in a single, unambiguous location within a system. The DRY principle advocates that: 1. **Single Source of Truth**: Each piece of information should be stored in one place only.
