Answer
- Use sequential
await - Implement locks or semaphores
- Avoid shared mutable state
- Use atomic operations
Quick Answer
Race conditions in async JS happen when two operations both modify shared state and the second overwrites the first's result. Prevention: flag a running request and cancel/ignore the previous one (AbortController), use optimistic locking (check a version/timestamp), use a queue to serialize operations, or avoid shared mutable state altogether (immutable updates).
