|-

'''The Concept of "Failing Fast"''': Analyzing why failing early is good. In TDD, you know you have a bug **one second** after you write it. In traditional coding, you might find that same bug 3 months later when the app crashes in production. The "Cost of a Bug" grows exponentially the longer it stays in the code.
