我有一个数组如下：

const arr = [
            {company: 'a', date: '1'},
            {company: 'b', date: '1'},
            {company: 'c', date: '1'},
            {company: 'a', date: '2'},
            {company: 'a', date: '1'},
            {company: 'b', date: '2'},
          ]

我只想知道如何在其中获取独特的对象。我尝试通过以下命令使用 lodash：

uniqBy(arr, 'date');

但它只返回：

[
  {company: "a", date: "1"},
  {company: "a", date: "2"}
]

我想要这样的东西：

[
  {company: "a", date: "1"},
  {company: "a", date: "2"},
  {company: "b", date: "1"},
  {company: "b", date: "2"},
  {company: "c", date: "1"},
]

在 lodash 或 vanilla JS 中有没有办法做到这一点？
