SessionStorage

Summary

Like LocalStorage but scoped to a single browser tab and cleared when that tab closes — useful for temporary, per-tab state. Its tab-level lifetime makes it useful for temporary workflows, multi-step forms, and state that should not automatically follow the user into another tab.

• 1Compare sessionStorage vs localStorage side by side in DevTools. Write down when you would choose each option and what trade-off drives that choice.
• 2Try storing form draft data in sessionStorage to survive a page refresh. Inspect the result in DevTools or the console and explain what you observed.
• 3Understand it doesn't persist across tabs, unlike localStorage.
