如何从类似whatsapp的消息列表中选择最后一条消息？

// 假设messages是从后端API获取到的消息列表数组
const messages = [
  { content: "Hello", sender: "Alice", receiver: "Bob", timestamp: 1631234567890 },
  { content: "Hi", sender: "Bob", receiver: "Alice", timestamp: 1631234578901 },
  { content: "How are you?", sender: "Alice", receiver: "Bob", timestamp: 1631234589012 }
];

// 按照时间戳降序排序消息列表
const sortedMessages = messages.sort((a, b) => b.timestamp - a.timestamp);

// 选择最后一条消息
const lastMessage = sortedMessages[0];

console.log(lastMessage);
