我应该订阅还是使用支持属性来更新组件中的依赖数据？

import React, { useEffect } from 'react';
import { useSelector, useDispatch } from 'react-redux';
import { fetchData } from './actions';

const MyComponent = () => {
  const data = useSelector(state => state.data);
  const dispatch = useDispatch();

  useEffect(() => {
    dispatch(fetchData());
  }, [dispatch]);

  return (
    <div>
      {data.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

export default MyComponent;

import React, { useState } from 'react';

const ParentComponent = () => {
  const [data, setData] = useState([]);

  const fetchData = async () => {
    const response = await fetch('https://api.example.com/data');
    const result = await response.json();
    setData(result);
  };

  return (
    <div>
      <button onClick={fetchData}>Fetch Data</button>
      <ChildComponent data={data} />
    </div>
  );
};

const ChildComponent = ({ data }) => {
  return (
    <div>
      {data.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
    </div>
  );
};

export default ParentComponent;
