Node.js

About

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside a web browser. It allows developers to use JavaScript for server-side programming, enabling the creation of scalable network applications.

It is primarily used for building fast and efficient back-end services, APIs, and real-time applications like chat servers. Node.js is suitable for web developers who want to use a single programming language across the entire web stack, from front-end to back-end development.
