    // while data stored in localStorage has no expiration set, data stored in sessionStorage gets
    // cleared when the page session ends. A page session lasts for as long as the browser is open
    // and survives over page reloads and restores. Opening a page in a new tab or window will
    // cause a new session to be initiated, which differs from how session cookies work.

    // The read-only **localStorage** property allows you to access a Storage object for the
    // Document's origin; the stored data is saved across browser sessions. localStorage is similar
    // to sessionStorage, except that while data stored in localStorage has no expiration time,
    // data stored in sessionStorage gets cleared when the page session ends — that is, when the
    // page is closed.
