# Lesson 1 complete; primaries deferred

Learner finished lesson 1 (when Cache API fits) and can work the choose/reject decisions for Cache Storage vs IndexedDB vs memory/Web Storage. Primary external reads (web.dev Storage for the web; Cache API quick guide) were **not** done this session. Next lessons should teach the API surface from cited sources and use the quick guide as the deferred primary — do not re-teach the full spectrum from zero.
