如何根据React (Firebase)中发布的日期/时间对评论进行排序？

import React, { Component } from 'react';
import firebase from './firebase';

class CommentList extends Component {
  constructor(props) {
    super(props);
    this.state = {
      comments: []
    };
  }

  componentDidMount() {
    const commentsRef = firebase.database().ref('comments');
    commentsRef.on('value', (snapshot) => {
      let comments = [];
      snapshot.forEach((childSnapshot) => {
        const comment = childSnapshot.val();
        comments.push(comment);
      });
      // 根据日期/时间字段对评论进行排序
      comments.sort((a, b) => a.timestamp - b.timestamp);
      this.setState({ comments });
    });
  }

  render() {
    return (
      <div>
        <h2>评论列表</h2>
        {this.state.comments.map((comment) => (
          <div key={comment.id}>
            <p>{comment.text}</p>
            <p>发布时间：{comment.timestamp}</p>
          </div>
        ))}
      </div>
    );
  }
}

export default CommentList;
