React.js

• A library for building user interfaces.
• Great for SPAs (Single Page Applications) where client-side
• rendering (CSR) is enough.
• Requires additional setup for routing, state management, and API
• handling (e.g., using React Router, Redux, etc.).
• More flexibility but requires manual configuration for things like SSR, SEO, and performance optimizations.

Next.js

• A framework built on top of React.
• Provides SSR (Server-Side Rendering), SSG (Static Site
• Generation), and ISR (Incremental Static Regeneration) for better SEO and performance.
• Comes with built-in routing (file-based), API routes, and full-stack capabilities.
• Ideal for fast-loading, SEO-friendly websites, such as e-commerce platforms, blogs, and dashboards.
