What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization standard. It's commonly used for configuration files and data exchange between languages with different data structures.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for humans to read and write, and easy for machines to parse and generate.
