#NodeJS

Node.js is a cross-platform, open-source JavaScript runtime environment that can run on Windows, Linux, Unix, macOS, and more. Node.js runs on the Chrome’s V8 JavaScript engine, and executes JavaScript code outside a web browser. It is a free, open-source, cross-platform JavaScript runtime environment licensed under MIT License that lets developers create servers, web apps, command line tools and scripts.

Node.js lets developers use JavaScript to write command line tools and for server-side scripting. The ability to run JavaScript code on the server is often used to generate dynamic web page content before the page is sent to the user’s web browser. Consequently, Node.js represents a “JavaScript everywhere” paradigm, unifying web-application development around a single programming language, as opposed to using different languages for the server- versus client-side programming.
