What aspect of local storage allows data to persist even after the web page is closed?

The aspect of local storage that allows data to persist even after the web page is closed is known as Persistent Storage. Unlike session storage, which retains data only for the duration of the page session and is cleared when the tab or browser is closed, persistent storage is specifically designed to store data that should remain available even when the user navigates away from the web page or closes the browser.

Persistent storage works by saving key-value pairs in the browser, which can later be retrieved as needed, making it useful for applications that require long-term storage of data such as user preferences, settings, or any information that should be retained across sessions.

This feature is critical in modern web applications, allowing for a more seamless user experience by remembering the user's choices and states, thereby enhancing the overall usability of the application.
