Session storage is similar to local storage, but the stored data is only available for the duration of the browser session. When the user closes the browser window or tab, the data is cleared. Session storage is typically used to store information that only needs to be available while the user is browsing the website, such as shopping cart contents, user login information, and other data that should be cleared when the user logs out or closes the browser.
Session storage is also a key-value store, but it is limited to the current browser tab or window. Data stored in session storage is not accessible to other tabs or windows running under the same origin, which provides additional security and privacy protection.
In summary, local storage and session storage provide developers with a way to store data on the client-side browser, allowing for a more responsive and customized user experience. Local storage is used for long-term data storage, while session storage is used for short-term data storage. Both are key-value stores that are limited by the size of the browser storage and are accessible only within the current website or browser tab.
