-      Server Components in allow developers to write components that render on the server instead of the client. Unlike traditional components, Server Components do not have a client-side runtime, meaning they result in a smaller bundle size and faster loads. They can seamlessly integrate with client components and can fetch data directly from the backend without the need for an API layer. This enables developers to build rich, interactive apps with less client-side code, improving performance and developer experience.
