Assumptions/Comments

• This project assumes the JSON response from the book API will be an array where each item contains nested book and stock objects, structured as follows:

  {
    "book": {
      "title": "Macbeth",
      "author": "William Shakespeare",
      "isbn": "123456789"
    },
    "stock": {
      "quantity": 5,
      "price": "6.99"
    }
  }

• The client maps this response to a simpler object containing only these properties:

  {
    "title": "Macbeth",
    "author": "William Shakespeare",
    "isbn": "123456789",
    "quantity": 5,
    "price": "6.99"
  }
