A structured lesson workspace with readable content, hands-on examples, and a clean path to completion.
| Question to ask | Good diagnostic move |
|---|---|
| What value entered? | Inspect the runtime value and type. |
| What rule applied? | Check the construct's language or host semantics. |
| What changed? | Compare the smallest working and failing cases. |

<strong>Core idea:</strong> Projects are where individual JavaScript techniques meet. Each capstone is deliberately shaped around a real feature set, an obvious failure mode, and a production concern. In this lesson, the practical target is building a full-stack javascript application: you should be able to predict what the runtime will do before changing the code.

Mentor note: for building a full-stack javascript application, name the invariant you need before reaching for a clever shortcut. Clear state and explicit assumptions make later debugging much cheaper.
