Explain what JSON abbreviation means and what it is used for.

JSON (JavaScript Object Notation) is a text-based data interchange format based on the syntax of JavaScript objects. It is used for storing and transmitting structured data between a client and a server or between different systems.

JSON is convenient because:

• It is easily readable by humans
• It is easy to parse and generate by programs
• It is a language-independent format

Example of a JSON object:

{
  "name": "Ivan",
  "age": 30,
  "isStudent": false,
  "skills": ["Python", "Java"]
}

In Python, the json module is used to work with JSON, which allows converting Python objects to JSON strings and vice versa.
