如何根据新帖子和新评论对帖子进行排序

// 假设我们有一个帖子列表和每个帖子的评论列表
const posts = [
  {
    id: 1,
    title: 'Post 1',
    timestamp: new Date('2023-10-01T10:00:00Z'),
    comments: [
      { id: 1, text: 'Comment 1', timestamp: new Date('2023-10-01T10:05:00Z') },
      { id: 2, text: 'Comment 2', timestamp: new Date('2023-10-01T10:10:00Z') }
    ]
  },
  {
    id: 2,
    title: 'Post 2',
    timestamp: new Date('2023-10-01T09:55:00Z'),
    comments: [
      { id: 3, text: 'Comment 3', timestamp: new Date('2023-10-01T10:03:00Z') }
    ]
  }
];

// 根据帖子的时间戳进行排序
posts.sort((a, b) => b.timestamp - a.timestamp);

// 根据评论的时间戳进行排序
posts.forEach(post => {
  post.comments.sort((a, b) => b.timestamp - a.timestamp);
});

console.log(posts);

const express = require('express');
const app = express();

// 假设我们有一个帖子列表和每个帖子的评论列表
let posts = [
  {
    id: 1,
    title: 'Post 1',
    timestamp: new Date('2023-10-01T10:00:00Z'),
    comments: [
      { id: 1, text: 'Comment 1', timestamp: new Date('2023-10-01T10:05:00Z') },
      { id: 2, text: 'Comment 2', timestamp: new Date('2023-10-01T10:10:00Z') }
    ]
  },
  {
    id: 2,
    title: 'Post 2',
    timestamp: new Date('2023-10-01T09:55:00Z'),
    comments: [
      { id: 3, text: 'Comment 3', timestamp: new Date('2023-10-01T10:03:00Z') }
    ]
  }
];

app.get('/posts', (req, res) => {
  // 根据帖子的时间戳进行排序
  posts.sort((a, b) => b.timestamp - a.timestamp);

  // 根据评论的时间戳进行排序
  posts.forEach(post => {
    post.comments.sort((a, b) => b.timestamp - a.timestamp);
  });

  res.json(posts);
});

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
