What will I learn?

This course teaches safe improvement of legacy code without changing its behaviour. Learners identify code smells, craft small pure functions, and reorganise discount calculations with distinct duties. Using targeted unit tests, characterisation tests, CI pipelines, and brief documentation, you build an effective process to refactor swiftly, cut down bugs, and simplify upcoming modifications.
