HTML Web Storage API provides a way for web applications to store and access data locally in the user’s web browser. There are two types of storage available in the Web Storage API: localStorage and sessionStorage.
The localStorage object stores data without an expiration date. This means that the data will not be deleted when the browser is closed, and will remain available even after the computer is restarted. The localStorage object provides two methods for accessing data: setItem() and getItem().
The sessionStorage object stores data for a session. This means that the data will be deleted when the browser is closed, and will not be available after the computer is restarted. The sessionStorage object provides the same two methods for accessing data: setItem() and getItem().
