What will I learn?

This course teaches you to improve old code safely without changing how it works. You will identify code smells, create small pure functions, and reorganise discount calculations clearly. Using unit tests, characterisation tests, CI processes, and clear documentation, you develop a workflow to refactor quickly, cut bugs, and simplify future updates.
