React.js and Node.js are both popular JavaScript technologies, but they serve different purposes.
React.js
React.js is a JavaScript library for building user interfaces. It allows developers to build reusable UI components that can be easily composed to create complex user interfaces. React uses a virtual DOM to efficiently update the view when the state of the application changes, which makes it particularly well-suited for building high-performance web applications.

Node.js
Node.js, on the other hand, is a JavaScript runtime that allows developers to run JavaScript on the server-side. It allows developers to use JavaScript to write server-side code, including creating and running web servers, interacting with databases, and more. Node.js is known for its fast and efficient performance, making it a popular choice for building real-time and high-performance applications.

Conclusion React.js vs Node.js
In summary, React.js is a JavaScript library for building user interfaces, while Node.js is a JavaScript runtime for running JavaScript on the server-side. Both technologies are widely used in web development and can be used together to create full-stack JavaScript applications.
