I was asked this

Where should a React Native app store user preferences, auth tokens and offline data?

🎤 Answer it out loud, then check yourself

Say your answer as if the interviewer is listening (30–90 seconds). Then reveal what a strong answer covers and tick what you said.

    Try it · run and change it
    // Pick the right storage for each kind of data
const where = {
  theme: "AsyncStorage or MMKV (small, not secret)",
  authToken: "SecureStore / Keychain (encrypted)",
  offlineMessages: "SQLite or WatermelonDB (structured, queryable)",
  apiCache: "TanStack Query with a persister",
};
for (const [data, store] of Object.entries(where)) console.log(data.padEnd(16), "→", store);
    Answer out loud first, then compare.
