How can I create interfaces for deeply nested objects in TypeScript?

Check out my current JSON data below:

{
  "state_1": {
    "date": [
     {
          1000: {
            "size": 3,
            "count": 0
          }
        },
      {
          1001: {
            "size": 3,
            "count": 1

          }
        }
      ]
}

How do I define the Example interface to represent a structure where state has a date property containing a list of id (such as 1000 and 1001) that hold string values for size and count.

If you're dealing with undefined key definitions, employing an index signature can prove to be quite handy.

interface Directory {
    records: {
        [identifier: number]: {
            dimensions: string;
            quantity: string;
        }
    }[];
}
