Your question is Frontend Component for Streaming Data. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you architect a front-end component that handles streaming data updates in real time at scale?
Assume the component powers a high-traffic Amazon surface that shows continuously updating events to users. Focus on how the UI stays responsive under bursty updates, reconnects cleanly, and avoids rendering stale or duplicated data.
