2, storage size limit is different, cookie data can not exceed 4K, and because every http request will carry the cookie, so the cookie is only suitable for preservation small data, such as a session identifier. Although sessionStorage and localStorage storage size is also limited, but is much larger than the cookie, you can reach 5M or greater
3, different data is valid, sessionStorage: only valid until the current browser window is closed; localStorage: always active window or browser Close has been saved, so as a persistent data; cookie: cookie is only valid until the expiration time set, even if the window is closed or the browser is closed
4, different scopes, sessionStorage not different browser window to share, even with a page; localstorage in all homologous windows are shared; cookie is homologous in all windows are shared
