Can you explain what the JSON format is and what it is used for?

JSON (JavaScript Object Notation) is a text format for storing and exchanging data, based on the syntax of JavaScript objects but used in many programming languages.

Main features of JSON:

• Easy for humans to read and write.
• Structured as key-value pairs.
• Supports data types: strings, numbers, booleans, arrays, objects, and null.

JSON is widely used for data exchange between client and server in web applications, as well as for storing configurations and data.

Example of JSON:

{
  "name": "Ivan",
  "age": 30,
  "isStudent": false,
  "courses": ["Mathematics", "Physics"]
}
