What will I learn?
This course teaches safe improvement of legacy code while keeping its original behaviour intact. Learners 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, participants build an effective process to refactor swiftly, cut down bugs, and simplify upcoming modifications.
