Node.Js is an open-source, cross-platform framework. That allows developers to build server-side applications using JavaScript. Node.Js was created by Ryan Dahl in 2009 and has since become a popular tool for building fast and scalable web applications.
Moreover, the V8 JavaScript engine, the same engine used by Google Chrome to run JavaScript code, is the foundation upon which Node.js is constructed. Because of its great performance and scalability, Node.js is perfect for developing apps that need real-time data processing or numerous concurrent connections.
