如何使用react useState钩子防止竞争条件

const [count, setCount] = useState(0);

// 使用函数形式的更新
setCount(prevCount => prevCount + 1);

const initialState = { count: 0 };

function reducer(state, action) {
  switch (action.type) {
    case 'increment':
      return { count: state.count + 1 };
    case 'decrement':
      return { count: state.count - 1 };
    default:
      throw new Error();
  }
}

function Counter() {
  const [state, dispatch] = useReducer(reducer, initialState);

  // 使用dispatch来更新状态
  const handleIncrement = () => {
    dispatch({ type: 'increment' });
  };

  const handleDecrement = () => {
    dispatch({ type: 'decrement' });
  };

  return (
    <div>
      <p>Count: {state.count}</p>
      <button onClick={handleIncrement}>Increment</button>
      <button onClick={handleDecrement}>Decrement</button>
    </div>
  );
}
