Answer

  • Non-blocking Operations: Using async methods allows DOM updates without freezing the UI.
  • Performance: Reduces reflows and repaints, enabling smoother transitions and animations.
  • User Experience: Improves responsiveness; users can interact while background tasks complete.
  • Trade-offs: Managing consistency of state can become complex; ensure async operations correctly handle UI updates.
