YAML and JSON are two widely used formats in the world of data serialization. Both have their unique features and use cases.

JSON (JavaScript Object Notation)#

JSON uses a combination of curly braces {}, square brackets [], and key-value pairs separated by colons :. It is commonly used in web applications to transmit data between a server and a client due to its lightweight nature and ease of use with JavaScript.

Example of a JSON object:

{
  "name": "Rabi",
  "age": 25,
  "married": false,
  "pets": ["Tom", "Jerry"],
  "address": {
    "street": "123 Main St",
    "city": "Gujranwala"
  }
}

YAML (YAML Ain’t Markup Language)#

YAML uses indentation (usually with spaces) to denote structure and relies on colons : for key-value pairs. It is designed to be human-readable and is often used for configuration files due to its simplicity and readability.

Example of a YAML document:

name: Rabi
age: 25
married: false
children:
  - Tom
  - Jerry
address:
  street: 123 Main St
  city: Gujranwala

Data Types#

• JSON: Limited to basic data types (string, number, object, array, boolean, null).
• YAML: Supports complex data types and references, making it more flexible for certain use cases.
