Perfect Answer:

For the real-time chat feature, I started by understanding the application’s architecture. I implemented a WebSocket-based solution for real-time communication and integrated it with the backend using Node.js. Frontend components were built with React to provide a dynamic user interface. This approach ensured a smooth integration of the chat feature into the existing application, enhancing user engagement.
