Great job! We can store some complicated objects in JSON files. Have a look at this example:

{
  "author": {
    "first_name": "Guido",
    "last_name": "van Rossum"
  },
  "title": "An Introduction to Python",
  "pages": 175,
  "ISBN-10": 915215643
}

Here we have information about a book. What's the difference between this example and the previous ones? Inside our object, we have a key named author, which has a nested JSON object passed as a value.

{
  "first_name": "Guido",
  "last_name": "van Rossum"
}

That nested object itself contains name-value pairs. If the book has multiple objects, we can group the author values into one array, like this:

{
"author": [
    {
      "first_name": "Guido",
      "last_name": "van Rossum"
    },
    {
      "first_name": "Alex",
      "last_name": "Smith"
    }
  ]
}
