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.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without having to switch platforms... I appreciate everything you do, I've already recommended you to others...
