sessionStorage is similar to localStorage ; the difference is that while data in localStorage doesn't expire, data in sessionStorage is cleared when the page session ends. Whenever a document is loaded in a particular tab in the browser, a unique page session gets created and assigned to that particular tab.
#Save Data to Session Storage ->sessionStorage.setItem("key", "value");
#Read Data from Session Storage ->let lastname = sessionStorage.getItem("key");
#Remove Data from Session Storage ->sessionStorage.removeItem("key");
#Remove All (Clear session Storage) ->sessionStorage.clear();
