Working with Node.js
Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a browser. Node.js enables developers to use JavaScript to write command line tools and to utilize server-side scripting to create dynamic web page content before the page is sent to the user's web browser. This path will take you from the basics of Node.js to writing and testing asynchronous Node.js code.
