a dedicated TypeScript interface for a particular JSON schema

I am pondering, how can I generate a TypeScript interface for JSON data like this:

  "Cities": {

        "NY": ["New York", [8000, 134]],

        "LA": ["Los Angeles", [4000, 97]],

    }

I'm uncertain about how to handle these nested arrays and unique identifiers.

Answer №1

To define the elements that an array will hold, you can use the following syntax:

interface IData {
  [key: string]: [
    string,
    [number, number]
  ];
}

The notation [number, number] specifies that the array contains exactly two elements of type number. This is different from number[], which signifies an array of number elements.
