NodeJs is a runtime environment and library for running JavaScript applications outside of the browser. It is used by companies such as IBM, Microsoft, PayPal, and Netflix. Node.js is open-source and available under the MIT license.
Node.js was created in 2009 by Ryan Dahl. It was originally called V8Js but later renamed to Node.js to avoid confusion with the Google V8 JavaScript engine. The first commit to the Node.js repository was made on February 21, 2009.
Node.js is a platform built on Chrome’s V8 JavaScript engine. It uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Applications run on Node.js are written in JavaScript and can use Node.js modules to access system resources like files, sockets, and processes.
Node.js has become increasingly popular in recent years. It is used by some of the world’s largest companies and has a large community of contributors. Node.js is also available on Windows, Mac, and Linux.
