What is YAML vs JSON?
YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats, but they serve different use cases. YAML uses indentation-based syntax and supports comments, making it popular for configuration files (Kubernetes, Docker Compose, Ansible, GitHub Actions). JSON uses braces and brackets, is more compact, and is the standard for APIs and data interchange. Converting between them is a common task when moving data between config files and application code.
