Use when a task that changed backend code is finishing, before reporting it done. Symptoms — a migration was added, a request or response shape changed, a new route exists, a cache key was added, something could not be verified, a problem was found and deliberately left alone.
Use when adding or changing a protected route, a guard, a role check, or any query that reads or writes records belonging to a user or tenant. Symptoms — a findById that takes only an id, a route with no guard, a role checked in the controller but not the query, an ID read straight from params, a new public endpoint, a service method reachable from more than one caller.
Use when choosing which exception to throw, shaping an error response, or deciding what to log. Symptoms — a caught error that returns 200, a try/catch that swallows the cause, a 500 where the client should see 400, an error message exposing a stack trace or SQL, a log line with no request context, the same failure logged at every layer.

Khi có tính toán nặng lặp lại, hoặc cần giữ tham chiếu ổn định cho props của component đã memo.
useMemo cho giá trị tính toán tốn kém hoặc object/array cần ổn định tham chiếu.useCallback cho hàm truyền xuống component đã memo hoặc làm dependency của effect.memo cho component con render thường xuyên với props ổn định.const sorted = useMemo(() => heavySort(items), [items]);
const onChange = useCallback((v: string) => setQuery(v), []);
const Child = memo(ChildBase);
Good: memo hoá kết quả sort lớn, callback ổn định cho child memo.
Avoid: useMemo cho phép cộng đơn giản, useCallback khắp nơi không có child memo.
