What is YAML?

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

  • ✅ Human-readable and easy to write
  • ✅ Supports comments
  • ✅ Uses indentation for structure
  • ✅ Popular for Docker, Kubernetes, CI/CD configs

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format. It's easy for both humans and machines to read and write, making it the standard for APIs and web applications.

  • ✅ Universally supported across languages
  • ✅ Compact and efficient
  • ✅ Built into JavaScript
  • ✅ Standard format for REST APIs
