What will I learn?
This course teaches safe improvement of legacy code while keeping its behaviour intact. You'll identify code smells, craft small pure functions, and reorganise discount calculations with distinct responsibilities. Using targeted unit tests, characterisation tests, CI pipelines, and succinct docs, you'll build a workflow to refactor swiftly, cut bugs, and simplify future updates.
