📦 Surprising Fact 2: Flexibility with Rendering

Next.js distinguishes itself by offering developers unparalleled flexibility in rendering strategies. Unlike traditional React applications that rely solely on client-side rendering (CSR), Next.js supports a blend of rendering techniques, enabling you to choose the optimal approach for each page or component.

• Server-Side Rendering (SSR): Render pages on the server for each request. This ensures that users receive fully rendered HTML, improving SEO and perceived performance, especially for content-heavy pages.
• Static Site Generation (SSG): Generate pages at build time. Ideal for content that doesn't change frequently, such as blog posts or documentation. SSG offers excellent performance and scalability.
• Incremental Static Regeneration (ISR): A hybrid approach that combines the benefits of SSG and SSR. Pages are statically generated but can be revalidated at specified intervals, ensuring content freshness without sacrificing performance.
• Client-Side Rendering (CSR): Render specific components on the client-side, useful for highly interactive elements or dynamic content that requires frequent updates.

This flexibility empowers you to optimize your application for various use cases, balancing performance, SEO, and user experience. For example, you might use SSG for your marketing pages, SSR for your product pages, and CSR for interactive dashboards.

By strategically employing these rendering techniques, Next.js enables you to build highly performant, SEO-friendly, and user-centric web applications.
