What is the difference between React.js and Next.js?

Next.js and React.js are two popular JavaScript technologies, and are essential for web development

React.js

1. Client-side JavaScript library: React.js is a front-end library for building user interfaces and single-page applications.
2. Component-based architecture: React.js encourages breaking down the UI into reusable components.
3. Virtual DOM: React.js uses a virtual DOM to optimize rendering and improve performance.
4. Used for: Building reusable UI components, single-page applications, and progressive web apps.

Next.js
1. React-based framework: Next.js is a framework built on top of React.js, extending its capabilities.
2. Server-side rendering (SSR): Next.js allows for server-side rendering, enabling faster page loads and improved SEO.
3. Static site generation (SSG): Next.js also supports static site generation, allowing for pre-rendered pages.
4. Routing and API routes: Next.js provides built-in routing and API routes, making it easier to handle client-server interactions.
.

Take home👇

1. React.js is for client-side development, creating the user interface and frontend of an application.
2. Next.js provides additional features like routing and API routes, making it a more comprehensive framework.

When to use😏

1. React.js: Building complex, interactive client-side applications.
2. Next.js: Building server-side rendered, statically generated, or performance-critical applications, while still leveraging React.js components.
