What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format using key-value pairs with curly braces and square brackets. It's the default format for REST APIs and data transmission.

What is YAML?

YAML (YAML Ain't Markup Language) uses indentation for structure, making it more human-readable. It's preferred for configuration files in Kubernetes, Docker, Ansible, and CI/CD tools.
