JSON (JavaScript Object Notation)

JSON, short for JavaScript Object Notation, is a lightweight data-interchange format that is easy for humans to read and write and for machines to parse and generate. It is often used to transmit data between a server and a web application as an alternative to XML.

In JSON, data is represented as key-value pairs enclosed within curly braces {}. Each key is a string enclosed in double quotes "", followed by a colon :, and then the corresponding value. Values can be strings, numbers, objects, arrays, booleans, or null.

Example

{
 "name": "John",
 "age": 30,
 "is_student": false,
 "favorite_fruits": ["apple", "banana", "orange"],
 "address": {
 "city": "New York",
 "zipcode": "10001"
}

JSON's simplicity and versatility make it popular for data exchange in web development, APIs, and many other applications. Its structure is easy for humans and machines to understand, making it an efficient and widely adopted format for transmitting and storing structured data.
