This question evaluates skills in frontend component state design, data modeling, pricing computation, validation logic, error handling, and API integration for a lodging reservation widget.

Implement a lodging reservation widget with: (

  1. inputs for check-in and check-out dates; compute total price based on nightly rate, length of stay, and dynamic pricing that changes with selected adults and children; (
  2. validation that check-out is after check-in and that guest counts do not exceed capacity; (
  3. a disabled “Book Now” button when the room is sold out or selection is invalid; (
  4. a confirmation dialog on submit. Describe component state, data models, and error states; outline how you would test edge cases such as minimum nights, partial availability, timezone/daylight-saving transitions, and price rounding.
