显示redux数据子集的最佳方式是什么？

import React from 'react';
import { connect } from 'react-redux';
import { fetchPosts } from '../actions/postsActions';

class PostsList extends React.Component {
  componentDidMount() {
    // 在组件挂载后，调用action creator来获取数据
    this.props.fetchPosts();
  }

  render() {
    const { posts } = this.props;

    return (
      <div>
        <h1>Posts List</h1>
        {posts.map(post => (
          <div key={post.id}>
            <h3>{post.title}</h3>
            <p>{post.body}</p>
          </div>
        ))}
      </div>
    );
  }
}

const mapStateToProps = state => ({
  posts: state.posts // 将Redux store中的posts数据映射到组件的props中
});

const mapDispatchToProps = {
  fetchPosts // 将fetchPosts action creator映射到组件的props中
};

export default connect(mapStateToProps, mapDispatchToProps)(PostsList);
