如何在筛选重复项时将对象数组拆分为多个对象数组？

function splitArrayByDuplicates(arr, property) {
  const obj = {};
  arr.forEach(item => {
    const key = item[property];
    if (!obj[key]) {
      obj[key] = [item];
    } else {
      obj[key].push(item);
    }
  });

  const duplicateArrays = Object.values(obj).filter(items => items.length > 1);

  const result = duplicateArrays.map(items => {
    return items.map(item => ({ ...item }));
  });

  return result;
}

// 示例用法
const originalArray = [
  { id: 1, name: 'A' },
  { id: 2, name: 'B' },
  { id: 3, name: 'C' },
  { id: 4, name: 'A' },
  { id: 5, name: 'D' },
  { id: 6, name: 'B' },
];

const splitArrays = splitArrayByDuplicates(originalArray, 'name');
console.log(splitArrays);

[
  [
    { id: 1, name: 'A' },
    { id: 4, name: 'A' }
  ],
  [
    { id: 2, name: 'B' },
    { id: 6, name: 'B' }
  ]
]
