Your question is State Management in Web 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).
What strategies do you use for state management in complex web applications?
Explain how you decide where state belongs, how it flows between components and layers, and how you keep asynchronous data, user interactions, and derived state consistent. Include the architecture patterns, boundaries, and testing approach you would use, along with trade-offs between local component state, shared client state, and server-state management.
