description Overview

Extract Field

When several related fields are declared sequentially within a class, this refactoring groups them together and often suggests encapsulating them into a dedicated Value Object (VO) or Data Transfer Object (DTO). This improves the class's cohesion by logically grouping related data members, making the class definition cleaner and more semantic.

Introduce Parameter

When a method relies on external state or data that is currently accessed via global variables or poorly scoped context, this refactoring suggests promoting that dependency into a formal method parameter. This immediately improves testability and makes the method's dependencies explicit, adhering strictly to functional programming principles.
