What is Next.js and why use it? Next.js is a React framework that enables server-side rendering (SSR), static site generation (SSG), API routes, and more out-of-the-box. It simplifies React app development by providing a set of conventions and features that improve performance, SEO,

nd developer experience.

Why use Next.js?

• Server-Side Rendering (SSR): Automatically generates HTML on the server for

better SEO and faster initial load.

• Static Site Generation (SSG): Pre-renders pages at build time, improving

performance.

• Automatic Code Splitting: Only loads the necessary JavaScript for the current

page.

• File-Based Routing: Routing is based on the file system, making navigation easier.
• API Routes: Allows you to build API endpoints directly inside your Next.js app.
• Image Optimization: Automatically optimizes images for better performance.

Example:

npx create-next-app my-next-app

In this setup, the app can be SSR or SSG-enabled, providing better performance and SEO

out of the box.
