sessionStorage.setItem('tab-item1', 'TI-1');
sessionStorage.setItem('tab-item2', 'TI-2');

// Add items to local storage.
localStorage.setItem('domain-item1', 'DI-1');
localStorage.setItem('domain-item2', 'DI-2');

// Remove all items from both local and session storage.
sessionStorage.clear();
localStorage.clear();

// Output storage.
console.log(sessionStorage.length);
console.log(localStorage.length);
