# Lesson 1 complete; storage spectrum from web.dev

Learner finished lesson 0001 and read web.dev *Storage for the web*. Treat as known: when IndexedDB vs Cache API vs Web Storage vs memory vs cookies; IDB for structured app data; Cache for HTTP assets; avoid localStorage as a general DB. Did **not** read MDN basic terminology yet — that is the primary source for lesson 2. Next ZPD: databases, object stores, keys, and the open/upgrade lifecycle (schema as a design cost).
