description Overview

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.

Replace Type Parameter

When working with generic containers (like `List` or custom generic types), this refactoring allows you to systematically replace the type argument `T` with a concrete type or another generic type across all usages. It is vital for maintaining type safety when evolving generic APIs, ensuring that all consumers of the generic structure are updated correctly.
