Nesting Objects

You have learned to define an object schema with properties using the properties keyword, and added properties with string and integer types .

In this lesson, you will learn how to nest objects within objects. Let's divide the name property into the three separate components: firstName, lastName, and middleName

1{
2  "name": {
3    "firstName": "John",
4    "lastName": "Doe",
5    "middleName": "Smith"
6  }
7  "age": 25,
8}

Defining a Subchema

In JSON Schema, A subschema refers to a schema that is nested within another schema.

To nest objects within objects, you can define a property as an object with its own properties. We can call this nested object a subschema.

Example of Name subschema:

1{
2  ...
3  "name": {
4    "type": "object",
5    "properties": {...},
6  }
7}

Now, try to modify the name property on the side editor to add firstName, lastName, and middleName with type string.
