如何将具有相似键/值的数组中的对象转换为该数组中的数组

function convertArrayToObject(arr) {
  var newObj = {};

  // 遍历数组，将键值对提取出来存储在新对象中
  for (var i = 0; i < arr.length; i++) {
    var obj = arr[i];
    for (var key in obj) {
      if (newObj[key] === undefined) {
        newObj[key] = [];
      }
      newObj[key].push(obj[key]);
    }
  }

  // 将新对象转换为数组形式
  var newArr = [];
  for (var key in newObj) {
    newArr.push({ [key]: newObj[key] });
  }

  return newArr;
}

// 示例用法
var arr = [
  { key1: 'value1', key2: 'value2' },
  { key1: 'value3', key2: 'value4' },
  { key1: 'value5', key2: 'value6' }
];

var result = convertArrayToObject(arr);
console.log(result);

[
  { key1: ['value1', 'value3', 'value5'] },
  { key2: ['value2', 'value4', 'value6'] }
]
