code-refactoring

To refactor long functions without changing behavior, you extract methods to modularize them into smaller, testable units. This process improves readability and reduces tight coupling while preserving the original functionality.

The best way to remove duplicated logic during code refactoring is to enforce DRY and SOLID principles. This involves extracting shared code into modular units and applying clean-code practices to reduce coupling.

You need to validate behavior with tests before and after code refactoring whenever you extract methods or reduce duplication. This behavior-preservation step ensures functionality remains completely intact across modules and services.

Yes, you can apply design patterns to reduce tight coupling in services and libraries. Refactoring with these patterns enforces clean-code practices and keeps functionality intact while improving overall codebase maintainability.

To refactor codebases with tight coupling across modules, you apply SOLID principles and extract methods to create modular units. This reduces dependencies and improves testability while strictly preserving existing behavior.
