6.7 Recognize components of JSON-encoded data

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. JSON is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999 Edition. It's structured as follows:

In this example, you have an object with a key "name" that has a string value. The array "phoneNumbers" contains two strings each with a country code prefix. Another array "children" contains two objects each representing a child with their own names and addresses. JSON data structures can be complex and nested, depending on the application requires.
