To eliminate duplicated validation logic, you extract the repeated rules into a centralized, reusable utility function. All affected code paths then call this single validator to ensure consistent behavior and reduce redundancy.

The DRY principle aims to centralize knowledge and logic into a single, authoritative representation within a system. This practice significantly reduces code duplication and prevents inconsistencies across software projects and APIs.

Detecting copy and paste anti-patterns requires tooling support to scan modules and files for repeated patterns. Identifying these duplicated code blocks promotes targeted refactoring into shared, reusable components.

You should centralize hardcoded values into a configuration pattern when the same constants appear across multiple modules. Referencing a configuration file removes duplication and maintains consistent application rules.

Applying the DRY principle effectively requires a centralized guideline and tooling support to detect duplication consistently. These tools scan for repeated patterns across files to prompt necessary refactoring.
