How would you prevent search-as-you-type race conditions with AbortController?
WHAT IT TESTS: Canceling stale fetches to keep the UI consistent. ANSWER OUTLINE: Abort the previous request before each new keystroke, pass the fresh signal into fetch, and ignore the AbortError.
WHAT IT TESTS: Whether you understand request cancellation as a correctness tool, not just a performance optimization, and can apply it inside a reactive component. ANSWER OUTLINE: Store an AbortController in a ref or closure, abort before the next fetch, supply the new signal in fetch options, and guard resolution logic so an AbortError does not surface to the user. RED FLAG: Believing debounce eliminates all races, comparing timestamps or request IDs instead of native cancellation, or letting unhandled promise rejections crash the handler.
