Why understanding Incremental Static Regeneration (ISR) can help you build faster websites

As you may know, traditional static sites are fast but lack real-time content updates. On the other hand, fully dynamic sites can drastically slow down your performance.

ISR (Incremental Static Regeneration) offers a solution by allowing you to pre-render pages at build time and update them as new data comes in, providing the best of both worlds.

Why ISR Can Be Useful

Performance Boost: ISR allows you to serve static pages with lightning-fast load times while keeping content fresh.
Scalability: It efficiently handles content-heavy sites by regenerating only the necessary pages, reducing the load on your server.
SEO Benefits: Pre-rendered content ensures that your pages are fully optimized for search engines, enhancing your visibility.

How to Use ISR

To use ISR, you add the revalidate prop to getStaticProps. Here’s an example code snippet taken from the Next.js official documentation:
