如何以1分钟为间隔对js数组消息进行分组

// 假设数组名为messages
const messages = [
  { content: '消息1', timestamp: 1628760000000 },
  { content: '消息2', timestamp: 1628760060000 },
  { content: '消息3', timestamp: 1628760120000 },
  { content: '消息4', timestamp: 1628760180000 },
  // ...
];

const interval = 60000; // 1分钟的毫秒数
const startTime = messages[0].timestamp; // 假设起始时间为第一条消息的时间戳

const groupedMessages = {};

messages.forEach(message => {
  const timestamp = message.timestamp;
  const groupIndex = Math.floor((timestamp - startTime) / interval);

  if (!groupedMessages.hasOwnProperty(groupIndex)) {
    groupedMessages[groupIndex] = [];
  }

  groupedMessages[groupIndex].push(message);
});

const result = Object.values(groupedMessages).map(group => JSON.stringify(group));

console.log(result);
