Question 8

Describe the difference between a Cookie, Session Storage and Local Storage.

Answer 8

They are all stored on the client side. Cookies are small pieces of data represented in key-value pairs and expires.

SessionStorage is persistent data and scope only to current browser window.

LocalStorage is persistent data. Unlike cookies, the storage limit is far larger (at least 5MB) and information is never transferred to the server.

Local storage is per origin (per domain and protocol). All pages, from one origin, can store and access the same data.
