Daily Term: DRY Principle

DRY Principle

The DRY (Don’t Repeat Yourself) Principle encourages developers to avoid duplicating code by abstracting common functionality into reusable components. For example, instead of copying a validation logic across multiple functions, a developer might create a single validateInput function. DRY reduces maintenance effort and bugs by ensuring changes are made in one place, but over-abstraction can lead to overly complex code if not balanced.
