Refactoring
Captions available
The idea
Refactoring is a reorganization technique that simplifies a design without changing its functionality — the structure improves while the behavior holds still, and the pairing is the definition.
In practice
A tangled routine rewritten into clean pieces still computes the same answers.
Where people slip
The without-changing-functionality clause is the entire definition.
