#Large JavaScript projects need boundaries that keep change localized. Structure, dependency policy, environment configuration, version control, and deployment all reinforce those boundaries. In this lesson, the practical target is dependency management and versioning: you should be able to predict what the runtime will do before changing the code.#link

Runtime value	What value actually arrived?
Language rule	Which rule determines the result?

A useful habit here is to inspect the actual value or runtime state rather than trusting a name. The example below is intentionally small, so one changed line has an obvious effect.
