 Ajax (asynchronous JavaScript and XML) is a set of web development techniques using many web technologies on the client side to create asynchronous web applications. With Ajax, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. By decoupling the data interchange layer from the presentation layer, Ajax allows for web pages, and by extension web applications, to change content dynamically without the need to reload the entire page. In practice, modern implementations commonly use JSON instead of XML, due to the advantages of JSON being native to JavaScript.

 With that in mind, the best kind of data to store within cookies is small pieces of data that needs to be transmitted to the server, such as auth tokens, session IDs, analytics tracking IDs, GDPR cookie consent, language preferences that are important for authentication, authorization, and rendering on the server. These values are sometimes sensitive and can benefit from the `HttpOnly`, `Secure`, and `Expires`/`Max-Age` capabilities that cookies provide.
 
-`localStorage` and `sessionStorage` both implement the [Web Storage API interface](https://developer.mozilla.org/en-US/docs/Web/API/Web_Storage_API). Web Storages have a generous total capacity of 5MB, so storage size is usually not a concern. The key difference is that values stored in Web Storage are not automatically sent on HTTP requests.

 Hence Web Storage should not be used to store data that is relied on by the server for the initial rendering of the page if server-side rendering is being used (typically authentication/authorization-related information). `localStorage` is most suitable for user preferences data that do not expire, like themes and layouts (if it is not important for the server to render the final layout). `sessionStorage` is most suitable for temporary data that only needs to be accessible within the current browsing session, such as form data (useful to preserve data during accidental reloads).
