Program implements 4 functionalities:
- Retrieves user, product and shopping cart data from external API.
- Creates a data structure containing all available product categories and the total value of products of a given category.
- Finds a cart with the highest value, determines its value and full name of its owner.
- Finds the two users living furthest away from each other.
Implementation of retreving data is placed in fetchData.ts file while other functionality are in functions.ts. Every function contains set of tests to verify edge cases and common data. For run-time type-safety I used Zod library which automatically verify response from fakestoreapi.
