About

JSON (JavaScript Object Notation) is a lightweight, language-independent data exchange format derived from JavaScript and used to structure and transmit data between systems.

It represents data as key-value pairs and ordered arrays, supports various data types, and is widely used in web APIs, configuration files, and data storage.

YAML ("YAML Ain't Markup Language") is a human-readable data serialization language designed for representing structured data and exchanging it between systems and programming languages.

It uses indentation-based syntax with minimal structural characters, represents data using three core primitives such as mappings, sequences, and scalars, and includes features such as anchors and aliases for referencing data, along with a simple typing system for numbers, strings, and booleans.
