How does it help with complex nested IF statements?

It utilizes 'Guard Clauses' and early return patterns to flatten logic, making the code much easier to follow and maintain.

Can I use this skill on legacy codebases without tests?

The skill strongly recommends establishing a test suite before refactoring to ensure no regressions occur, though it can provide guidance on how to safely wrap legacy code in tests.

Is this skill limited to a specific programming language?

While the examples provided are in TypeScript, the refactoring principles such as Extract Method and Polymorphism are universal concepts applicable to most modern programming languages.

Does this skill change how my code functions?

No, the primary goal of refactoring is to improve the internal structure and readability of the code without changing its external behavior.

What kind of 'Code Smells' can this skill identify?

It specializes in identifying long methods, deeply nested conditionals (Arrow Code), primitive obsession, magic numbers, and feature envy.
