description Overview

Extract Package

This refactoring takes a group of related classes and interfaces and moves them into a brand new, dedicated package or module. It is a structural tool that enforces the Separation of Concerns principle at the highest level. It is crucial for managing the complexity of large applications by creating clear, isolated domains within the codebase.

Introduce Variable

When a complex expression or calculation is used multiple times, or when its intermediate result is needed for clarity, this refactoring pulls that expression into a named local variable. This dramatically improves the flow of data within a function, making the code easier to follow without sacrificing performance. It is a key tool for improving local comprehension.
