code-refactoring

Refactor long methods and deeply nested conditionals by applying the Extract Method technique to break them into smaller, well-named functions. This improves code maintainability and readability without altering external behavior.

Fix code smells like primitive obsession and feature envy by applying targeted refactoring techniques. You can resolve primitive obsession using Introduce Parameter Object, and address feature envy by moving methods to the class containing the affected data.

Safely refactor code by following a step-by-step process that emphasizes testing. Ensure you have comprehensive tests covering the code's current behavior before modifying its internal structure, verifying that external behavior remains unchanged.

Use Replace Conditional with Polymorphism during software development when you encounter complex conditional logic that switches based on object type. This refactoring technique moves conditional branches into subclass methods to simplify conditionals.

Yes, you can use these refactoring patterns on an inherited, poorly documented module. The techniques allow you to systematically improve code structure and understandability, reducing the risk of introducing bugs when adding new features.
