LocalStorage API vs SessionStorage API

Developers should use the LocalStorage API for client-side storage of non-sensitive data like user preferences, application state, or cached content to improve performance and user experience meets developers should use the sessionstorage api for temporary data that needs to persist across page reloads within a single tab or window, such as form inputs, user preferences during a session, or state management in single-page applications without server-side storage. Here's our take.

LocalStorage API
