description Overview

Change Parameter Type

This refactoring changes the expected type of an argument in a method signature (e.g., from `String` to `UUID`). The IDE automatically updates the method body to handle the conversion or throws errors at all call sites that pass the old, incompatible type, forcing the developer to explicitly handle the necessary type conversion logic.

Introduce Type Alias

When a complex type signature (e.g., `Map`) is used repeatedly, this refactoring allows you to alias it to a simple, descriptive name (e.g., `UserDirectory`). This doesn't change the underlying type but drastically improves the readability of function signatures and variable declarations, making the code read closer to natural language.
