You are creating a real-time chat application in Node.js where you need to broadcast binary data to multiple clients. How would you manage the binary data to ensure optimal performance and minimal memory usage?

To ensure optimal performance and minimal memory usage when broadcasting binary data in a real-time chat application, it's best to send binary data as raw bytes. Using a binary WebSocket library or converting to base64 can introduce unnecessary overhead, and serializing binary data as JSON is not efficient.
