How to create an array of type.instanceOf?

This doesn't work:

const documentReference = type.instanceOf(DocumentReference);

scope({
  user: {
    accounts: "documentReference[]",
  }
}

const documentReference = type.instanceOf(DocumentReference);

scope({
  user: {
    accounts: "documentReference[]",
  }
}

const documentReference = type.instanceOf(DocumentReference);

scope({
  user: {
    accounts: type.instanceOf(DocumentReference)[],
  }
}

const documentReference = type.instanceOf(DocumentReference);

scope({
  user: {
    accounts: type.instanceOf(DocumentReference)[],
  }
}

I only get it working without an array:

const documentReference = type.instanceOf(DocumentReference);

scope({
  account: {
    user: type.instanceOf(DocumentReference),
  }
}

const documentReference = type.instanceOf(DocumentReference);

scope({
  account: {
    user: type.instanceOf(DocumentReference),
  }
}

This is working 🎉:

type.instanceOf(Array<DocumentReference>)

type.instanceOf(Array<DocumentReference>)

Maybe it's worth adding this example also to the docs? https://arktype.io/docs/objects#instanceof @ArkDavid

This isn't safe because there's no way to know at runtime what the array is supposed to include. type.instanceOf creates a Type like any other, meaning you can just chain the standard .array() method off it like type.instanceOf(DocumentReference).array()
