Cookies, SessionStorage, and LocalStorage all are utilized to store information on the client side. Everyone has its very own capacity and lapse limit.

SessionStorage: Similar to Local storage yet terminates when the browser closed (not the tab).
Cookies: Stores information that must be sent back to the server with resulting demands.

Cookies are little content records that sites place in a browser for following or login purposes. In the interim, LocalStorage and SessionStorage are new objects, both of these are storage determinations however fluctuate in scope and duration. LocalStorage is changeless and website-specific explicit though SessionStorage just endures as long as the term of the longest open tab.

Cookies:

1) We can set the lapse time for every cookie.
2) The information is sent back to the server for each HTTP ask for (HTML, pictures, JavaScript, CSS, and so forth) expanding the measure of traffic among client and server.
3) As far as possible is for the whole cookie, including name, esteem, expiry date and so on. To help most browsers, hold the name under 4000 bytes, and the general cookie size under 4093 bytes.

SessionStorage:

1) It is like localStorage.
2) Changes are just accessible per window or tab in browsers like Chrome and Firefox. Changes made are spared and accessible for the present page, just as future visits to the site on a similar window. When the window is closed, the storage is erased.
3) The information is accessible just inside the window/tab in which it was set.
4) The information isn’t persevering, for example, it will be lost once the window/tab is closed. Like localStorage, it chips away at the same-cause arrangement. Along these lines, information put away may be accessible on a similar root.

LocalStorage:

1) Web storage can be seen straightforwardly as an enhancement for cookies, giving a lot more prominent storage capacity. Accessible size is 5MB which impressively more space to work with than a normal 4KB cookie.
2) The information isn’t sent back to the server for each HTTP ask for (HTML, pictures, JavaScript, CSS, and so forth) – diminishing the measure of traffic among client and server.
3) The information put away in localStorage holds on until expressly erased. Changes made are spared and accessible for all present and future visits to the site.
4) It chips away at the same-origin policy. In this way, information put away might be accessible on similar inception.
