js is an application runtime environment that helps you to write server-side applications in JavaScript. It is efficient, lightweight, and even scalable. You can reuse and share the code between the frontend and the backend of your applications will speed up the development process. Node.js is a server framework, and it’s free. It is usually used as a backend as it has multiple modules (NPM, Grunt, etc.) and a supportive community. It is also a simple language to learn and great for data streaming.
What makes Node.js different from JavaScript is that Node.js has different sets of API. In the browser, you have a variety of DOM/ Web API that helps you interact with UI. These API’s are suitable for backend development, e.g., HTTP request, streams, etc.
