How do you prevent race conditions in async operations?

Senior JavaScript
Quick Answer Race condition prevention: cancel the previous operation when a new one starts (AbortController for fetch), use a request ID and discard stale responses if a newer one arrives, sequence operations with a queue (only process next after previous completes), or use optimistic locking on shared state (check version before write, retry on conflict).

Answer

Use locking mechanisms, sequential awaits, atomic operations, or cancellation tokens. Prevents inconsistent updates when multiple async tasks modify shared resources.
