Your question is Async Data Flows in Full-Stack Apps. 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).
Explain how you handle asynchronous data flows in a full-stack application. Describe how data moves between the UI, HTTP client, backend services, databases, and background work, including concurrency, cancellation, ordering, retries, errors, and loading states. Compare at least two mechanisms you would use, and scope your answer to common web application runtimes and APIs.
