description Overview

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.

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.
