LocalStorage

LocalStorage and sessionStorage are web storage objects that allow developers to save key-value pairs in the browser. It is a type of web storage allowing JavaScript apps or sites to store and access data right in the browser without an expiration date which means that data stored in localStorage won't be cleared when the page is closed.
