A structured lesson workspace with readable content, hands-on examples, and a clean path to completion.
| Observation | Diagnostic question |
|---|---|
| Runtime value | What value actually arrived? |
| Language rule | Which rule determines the result? |
const response = await fetch('/api/tasks');if (!response.ok) throw new Error(`HTTP ${response.status}`);const tasks = await response.json();console.log(tasks);

Finish the lesson once you have worked through the material. This awards ★ 20 XP.
