What will I learn?
This course teaches you to enhance old code safely without changing its behaviour. You'll identify code smells, craft small pure functions, and reorganise discount calculations with distinct roles. Using targeted unit tests, characterisation tests, CI pipelines, and brief documentation, you'll build a solid process to refactor quicker, cut down bugs, and simplify upcoming updates.
