Serving up HTML and JSON

The video tutorial explains how to use Express to send HTML and JSON responses. It covers the use of response.send to render HTML directly in the browser and to send JSON data for code consumption. The tutorial includes a challenge to update routes to send HTML and JSON, followed by a solution and testing. The video concludes with a preview of serving entire directories in future lessons.
