Q: What are React hooks? A: React hooks are functions that allow functional components to utilize state and other React features. Q: What are the rules for applying hooks? A: Rules include using hooks at the top level and avoiding placement inside loops or conditions. Q: Which hook is used to implement lifecycle methods? A: The useEffect hook replaces lifecycle methods for side effects in functional components. Q: What is the syntax of the useState hook? A: The syntax is const [state, setState] = useState(initialState);. Q: Compare useReducer and useContext. A: useReducer manages complex state logic, while useContext is for sharing values like themes. Q: How are hooks used for optimization? A: Hooks like useMemo and useCallback optimize performance in React applications. Q: What are custom hooks, and when do we use them? A: Custom hooks are functions using hooks, created to reuse stateful logic across components. Q: How can shared state be achieved between components using hooks? A: Shared state between components is achieved by using the same custom hook. Q: How do you use useEffect to call a loading function just once? A: Pass an empty dependency array: useEffect(() => { /* loading logic */ }, []);. Q: Compare useState and useRef. A: useState manages state, while useRef is for accessing and interacting with a mutable object without causing a re-render.
