Node.js is an open-source server-side JavaScript runtime environment built on Chrome’s V8 JavaScript engine. Node.js is suitable for creating scripts that generate and render dynamic content and also read, open and close files on the server.

Node.js follows the event-driven architecture. It is also nonblocking, asynchronous, and lightweight, making it suitable for creating event-driven applications. Furthermore, Node.js is also cross-platform, single-threaded, and memory efficient.

Like Python, Node.js also has a REPL ( read, evaluate, print, loop ) virtual environment to execute and test simple tasks in Node.js and JavaScript. To launch the Node REPL we can simply do so by typing the word node on the command line. By doing so, we enter into this Node.js interactive environment and determine the version of Node.js that we are currently running.
