What is isomorphic React?

Isomorphic React (also known as Universal React) refers to the ability to run React code on both the client-side (in the browser) and the server-side. This approach offers several benefits, including improved SEO (search engines can crawl fully rendered content), faster initial load times (the server sends pre-rendered HTML), and a better user experience (a smoother transition as the client-side application takes over). Isomorphic React applications typically involve using Node.js on the server to render the initial HTML, which is then 'hydrated' by the React code running in the browser, allowing the client-side application to take over.
