Answer
Use functional updates, stable references with useRef, and memoized callbacks via useCallback.
Quick Answer
Stale closures happen when a function captures a variable at one point in time and that variable later changes — but the function still uses the old value. Fix: include all used variables in useEffect dependencies (exhaustive-deps), use refs for values that should always be current without triggering re-renders, or use the functional update form of state setters.
