What is the difference between NodeJS and ReactJS?

Node.js and React.js are two different technologies based on JavaScript technology. Both are used for different purposes. We use Node.js to construct back-end (server-side) code, whereas React is a front-end (client-side) library.

These technologies are often used in the same project in a popular web development stack, the MERN stack. The most significant advantage of learning both technologies is that you can work on server-side and client-side using the same programming language-JavaScript.

NodeJs is a backend to React's frontend websites in the MERN stack.

ReactJS

ReactJS is an open-source JavaScript library that builds one-page web apps, user interfaces, and frontends in full-stack web applications.

Every user interface in ReactJS is made from one or more React components. React components are either functions or classes that return HTML. This structure of React components increases the reusability of the code.

React components can also be nested to make complex applications by combining many small and simple components.

NodeJS

NodeJS is a back-end JavaScript runtime environment that runs on a V8 JavaScript engine. It executes JavaScript code outside a web browser. It’s usually used in making back-end services and backends for various applications.

It is used in many development stacks, such as MERN and MEAN stacks, because of its fast and scalable services.
