Great tutorial! Building a real-time “user is typing…” feature with Node.js, React, and Socket.io is such a valuable skill for modern developers. It’s impressive how seamlessly real-time communication can be implemented using sockets. This project is perfect for anyone learning interactive web apps. I highly recommend it to students taking WEB DEVELOPMENT COURSES who want hands-on experience with real-time functionality. It’s both practical and fun to build! a href="url">link text
