description Overview

Replace Type with Generic

When a piece of code handles multiple, but related, types (e.g., processing `List` and `List`), this refactoring allows you to generalize the type parameter, replacing the specific type with a generic placeholder `T`. This maximizes code reuse by abstracting the specific type while retaining type safety.

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.
