-————————————————————————————————————- Node.js is an open-source, cross-platform, JavaScript runtime environment that executes JavaScript code outside a web browser. Node.js lets developers use JavaScript to write command line tools and for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser.

Express.js, or simply Express, is a web application framework for Node.js. It is designed for building web applications and APIs. It has been called the de facto standard server framework for Node.js. Express runs between the server created by Node.js and the frontend pages of a web application. Express also handles an application's routing.
