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 is a data serialization language designed to be human friendly and work well with modern programming languages for common everyday tasks.
