Understanding the Red-Green-Refactor TDD cycle
TDD inverts the traditional process by first writing a failing test (Red), then writing just enough code to make it pass (Green), and finally cleaning up the code (Refactor).

Demo: Implementing an addition feature using TDD
A calculator's 'add' endpoint is built by writing a failing test, implementing minimal code to pass, and then refactoring the test with multiple cases to ensure correct logic.

Evaluating the pros and cons of adopting TDD
TDD leads to more testable solutions and cleaner architecture but requires discipline and team buy-in to overcome the initial temptation to write implementation code first.
