YAML
A human-friendly data serialization format commonly used for configuration files and data exchange.
In-Depth Explanation
YAML (YAML Ain't Markup Language) is a human-readable data serialization format. It's commonly used for configuration files where readability and ease of editing are priorities.
YAML features:
- Indentation-based structure (no brackets)

- References and anchors
- Type inference
Common uses:
- Configuration files (Docker, Kubernetes)
- CI/CD pipelines (GitHub Actions, GitLab)
- OpenAPI specifications

YAML vs JSON:
- YAML: More readable, comments, complex types
- JSON: Simpler, broader language support
- YAML is a superset of JSON
Syntax examples:
- Lists: use dashes (-)
- Maps: use colons (:)
- Strings: usually unquoted
- Multi-line: use | or >
