What are the advantages and disadvantages of server-side rendering in web applications?

Server-Side Rendering (SSR) in web applications has the following advantages:

• Fast initial page load: HTML is generated on the server and sent immediately to the client, improving content display time.
• Better SEO: Search engines receive the ready HTML, making indexing easier.
• Support for older browsers: No need to execute a large amount of JavaScript on the client.

Disadvantages:

• Increased server load: The server must generate HTML for each request, which may require more resources.
• Implementation complexity: Proper synchronization of state between server and client is necessary.
• Less interactivity without additional JS: Dynamic functions require additional client-side JavaScript.

Example: React applications with SSR use frameworks like Next.js, which allow rendering pages on the server and then hydrating them on the client for interactivity.
