Querying Data in Nested JSON: A Comprehensive Guide

To query the specified data in nested JSON, you can use dot notation to access nested properties. For example, if you have a JSON object like this:

{
  'name': 'John',
  'age': 30,
  'address': {
    'street': '123 Main St',
    'city': 'Anytown',
    'state': 'CA',
    'zip': '12345'
  }
}

You can access the 'street' property by using dot notation like this:

address.street

This would return '123 Main St'. Similarly, you can access other nested properties using dot notation. If you want to access nested arrays within the JSON object, you can use array indexing. For example, if you have a JSON object like this:

{
  'name': 'John',
  'age': 30,
  'friends': [
    {
      'name': 'Jane',
      'age': 28
    },
    {
      'name': 'Bob',
      'age': 32
    }
  ]
}

You can access the 'name' property of the first friend by using array indexing and dot notation like this:

friends[0].name

This would return 'Jane'. Similarly, you can access other nested properties within arrays using array indexing and dot notation.
