sessionStorage, IndexedDB, and Choosing the Right API
Compare browser storage options by persistence, capacity, and synchronous vs asynchronous access.
sessionStorage Shares the API
sessionStorage exposes the exact same methods as localStorage but its lifetime is tied to the tab. When the tab or window closes, its data is cleared automatically.
It is also isolated per tab, so two tabs do not share sessionStorage data.
A Multi-Step Form Use Case
sessionStorage shines for a multi-step wizard where you want to preserve progress across reloads within the session but discard it once the tab closes.
The user can refresh mid-form without losing entries, yet nothing lingers after they finish or leave.
