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 component re-render thừa, list lớn lag, hoặc tính toán nặng lặp lại.
useMemo cho tính toán nặng; useCallback cho callback truyền xuống child memo.React.memo cho child tốn kém nhận props ổn định.key ổn định, duy nhất (id thật, không dùng index khi list đổi thứ tự).lazy/Suspense) và virtualize list dài.const Row = React.memo(function Row({ item, onPick }: RowProps) {
return <li onClick={() => onPick(item.id)}>{item.label}</li>;
});
const handlePick = useCallback((id: string) => select(id), [select]);
const sorted = useMemo(() => heavySort(items), [items]);
Good: Row memo + handlePick useCallback ổn định + key={item.id}.
Avoid: key={index}, memo hóa mọi thứ vô tội vạ, callback mới mỗi render phá memo.
key ổn định, duy nhất (không dùng index khi list đổi)memo/useMemo/useCallback dùng đúng chỗ
