YAML vs JSON
YAML is more readable for humans. JSON is stricter and better for machines. Config files usually pick YAML; APIs pick JSON.

|---|---|---|
| Comments | Yes — # comments supported | No comments |
| Readability | Higher — indentation-based | Moderate — braces and quotes |
| Strictness | Loose — prone to indent bugs | Strict — syntax errors are obvious |
| Common use | Docker Compose, GitHub Actions, Kubernetes | REST APIs, web data |
| Nesting visual clarity | Higher | Lower with deep nesting |
