Node.js uses your web browser to make a request for a website on a Node.js web server. When the Node server accepts your request and calls a function to retrieve that file, the Node server waiting for the files to be retrieved services the next request. When the file is received, there is a callback function that is inserted in the Node servers queue. The Node server executives that function and sends it back to your web browser. This helps save milliseconds per request when dealing with highly-scalable web servers.
