YAML vs JSON
YAML (YAML Ain't Markup Language) and JSON (JavaScript Object Notation) are both data serialization formats used for configuration files and data exchange. YAML is more human-readable with its indentation-based syntax, while JSON is more widely supported in programming languages and APIs.
When to Use Each Format
- YAML: Configuration files (Docker Compose, Kubernetes, CI/CD), documentation, human-edited files
- JSON: API responses, data storage, JavaScript applications, programmatic generation
