Node

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that allows developers to run JavaScript on the server-side. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, ideal for building scalable network applications.

With Node.js, developers can write server-side applications using JavaScript, the same language used for client-side scripting. This makes it easy to create web servers, APIs, and other network-based applications with a consistent programming language. Node.js has a rich library of modules and tools available through its package manager, npm, making it easy to extend and enhance its functionality.

Node.js was developed by Ryan Dahl in 2009, and it has since gained popularity for its performance, scalability, and ease of use. It is widely used by developers to build web applications, back-end services, and other network-based software solutions.
