React Js : Components, JSX, State, Props, Hooks

Next.js and React.js are both popular tools in the world of web development, but they serve different purposes and have unique features. Here’s a comparison to help you understand their differences and when you might want to use each one:

React.js

Library: React is a JavaScript library for building user interfaces, particularly single-page applications.

Flexibility: React provides a lot of flexibility, allowing developers to choose their own tools and libraries for things like routing and state management.

Component-Based: React allows developers to build reusable UI components.

Client-Side Rendering: React is primarily focused on client-side rendering, though it can be configured to support server-side rendering with additional libraries.

Next.js

Framework: Next.js is a framework built on top of React, providing a more opinionated and feature-rich environment for building web applications.

Server-Side Rendering (SSR): Next.js has built-in support for server-side rendering, allowing pages to be pre-rendered on the server, which can improve performance and SEO.

Static Site Generation (SSG): Next.js supports static site generation, enabling the pre-rendering of pages at build time.

API Routes: Next.js includes an API layer, allowing you to create serverless functions and API endpoints within your application.

Routing: Next.js has a built-in file-based routing system, making it easier to set up and manage routes without additional libraries.

Image Optimization: Next.js includes built-in image optimization, automatically handling image resizing, optimization, and lazy loading.

Automatic Code Splitting: Next.js automatically splits your code into smaller bundles, improving load times.
