Sort Properties Which Could Be Undefined

[joni1802]

Hello everyone,

I am not quiet sure if my understanding of how the sorting is working is wrong or if Nuxt Content is doing something wrong.

So for example I have multiple markdown documents with the properties createdAt and updatedAt. These properties are added using a front matter block at the beginning of each document and the updatedAt property is optional.

Example:
I would like to sort by the newest updated documents.

const { data } = await useAsyncData(() =>
  queryContent("/")
    .sort({ updatedAt: -1 })
    .only(["createdAt", "updatedAt"])
    .find()
);

// Result
 [
  {
    "createdAt": "2023-03-03T00:00:00.000Z"
  },
  {
    "createdAt": "2023-04-09T00:00:00.000Z"
  },
  {
    "createdAt": "2023-04-05T00:00:00.000Z"
  },
  {
    "createdAt": "2023-05-12T00:00:00.000Z"
  },
  {
    "createdAt": "2023-04-12T00:00:00.000Z"
  },
  {
    "createdAt": "2022-02-03T00:00:00.000Z"
  },
  {
    "createdAt": "2022-03-14T00:00:00.000Z"
  },
  {
    "createdAt": "2022-02-04T00:00:00.000Z"
  },
  {
    "createdAt": "2023-04-05T00:00:00.000Z",
    "updatedAt": "2023-02-04T00:00:00.000Z"
  },
  {
    "createdAt": "2023-02-02T00:00:00.000Z",
    "updatedAt": "2023-02-03T00:00:00.000Z"
  }
]

It seems like undefined properties are newer then defined ones. Has any one an idea how to fix this?
