如何根据时间戳属性过滤对象数组(代码替代SQL lag over partition by - command)

function filterObjectsByTimestamp(objects) {
  let filteredObjects = [];
  let prevTimestamp = null;

  for (let i = 0; i < objects.length; i++) {
    const currentObject = objects[i];

    if (currentObject.timestamp !== prevTimestamp) {
      filteredObjects.push(currentObject);
      prevTimestamp = currentObject.timestamp;
    }
  }

  return filteredObjects;
}

// 示例用法
const objects = [
  { id: 1, timestamp: 1627832400 },
  { id: 2, timestamp: 1627832400 },
  { id: 3, timestamp: 1627836000 },
  { id: 4, timestamp: 1627839600 },
  { id: 5, timestamp: 1627839600 },
];

const filteredObjects = filterObjectsByTimestamp(objects);
console.log(filteredObjects);

[
  { id: 1, timestamp: 1627832400 },
  { id: 3, timestamp: 1627836000 },
  { id: 4, timestamp: 1627839600 },
]
