JSON (JavaScript Object Notation) is a lightweight data-interchange format used for structured data.
Example:
json
{
"name": "John",
"age": 30,
"isStudent": false,
"skills": ["Python", "JavaScript", "Java"],
"address": {
"city": "New York",
"zip": "10001"
}
}
JSON uses key-value pairs and is widely used in APIs and configuration files due to its simplicity and readability.
