Hooks (useState, useEffect, useContext, da sauransu) sune fasalullun React don sarrafa jimloli da ilantarwa a cikin abubuwan aiki — kuma suna aiki iri daya a cikin React Native. Fahimtar babun hooks yana da mahimmanci don gina abubuwan React Native.
const [count, setCount] = useState(0); // state + setter; setting it re-renders
const [user, setUser] = ();
// useEffect runs side effects (data fetching, subscriptions) after render
useEffect(() => {
fetchData(); // runs after render
// optional CLEANUP (returned function) — runs on unmount / before re-running
const sub = subscribe();
return () => sub.unsubscribe(); // CLEAN UP (prevent leaks)
}, [dependency]); // dependency array → when to re-run
// → [] = run once on mount; [dep] = run when dep changes; none = every render
useEffect yana sarrafa ilantarwa (bubugan fara da, tunatawa, timers) tare da jerin dogaro wanda ake amfani da shi domin sarrafa lokacin gudu, da aikace-aikacen tsaftace na zaɓi (muhimmi ne domin guje wa tashin haɗin gida).
useContext → consume context (shared data without prop drilling)
useRef → a mutable reference that persists across renders (e.g. reference a component,
store a value without re-rendering)
useMemo → memoize an expensive computed value (performance)
useCallback → memoize a function (avoid unnecessary re-creation/re-renders)
useReducer → manage complex state with a reducer
CUSTOM HOOKS → extract reusable stateful logic (e.g. useFetch, useAuth)
⚠️ Only call hooks at the TOP LEVEL of a component (not in conditions/loops/nested functions)
⚠️ Only call hooks from React components or custom hooks
→ These rules ensure hooks work correctly (React relies on call order).
