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.

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

I like how the lessons get straight to the point and how I can switch chapters and skip content I don't need.
