What will I learn?
This course teaches safe improvement of old code without changing its behavior. Learners identify code smells, create small pure functions, and reorganize discount calculations clearly. Using unit tests, characterization tests, CI processes, and brief documentation, you build a workflow to refactor quickly, cut bugs, and simplify future updates.
