What will I learn?

This Code Refactoring Course shows you how to safely improve legacy code while preserving behavior. You will learn to spot code smells, design small, pure functions, and restructure discount calculations with clear responsibilities. Through focused unit tests, characterization tests, CI workflows, and concise documentation, you gain a practical workflow to refactor faster, reduce bugs, and make future changes easier.
