Server-side rendering entails generating the complete HTML content of a web page on the server in response to a user’s request. In contrast, client-side rendering constructs the page within the user’s web browser using JavaScript. Each approach has its merits and drawbacks, influencing factors like initial page load speed, search engine optimization (SEO), and interactivity. Server-side rendering is typically faster for initial page loads, while client-side rendering offers a more interactive user experience.
