Modern JavaScript from the Beginning - Second Edition - http Module

The video tutorial introduces the HTTP module in Node.js, explaining its limitations for production environments and the advantages of using Express. It demonstrates creating a simple server, handling requests and responses, and implementing basic routing. The tutorial also covers serving files using the FS module and creating a basic API endpoint with JSON responses. The instructor emphasizes the importance of understanding low-level operations before moving to frameworks like Express.
