The article demystifies client-side storage by contrasting SessionStorage, which holds data only for the current tab/session and clears on close, with LocalStorage, which persists until explicitly removed; it outlines when to use each (e.g., carts vs. user preferences), provides simple JS get/set examples, and shows how combining both improves UX in apps like e-commerce.
Comprehensive guide to IndexedDB for full‑stack devs: why client‑side storage matters for PWAs and offline‑first UX; how its NoSQL key‑value model, transactions, async API, indexes and IDBKeyRange enable fast queries on large structured data; practical steps to open DBs, define object stores, do CRUD and queries; pitfalls like quotas, serialization, and error handling; includes a fitness app offline‑sync example.
