JSON (JavaScript Object Notation) is a lightweight data format. It uses key-value pairs: {"name": "John"}. JSON is strict about syntax - requires double quotes and no trailing commas.
YAML (YAML Ain't Markup Language) is a human-readable data format. It uses indentation: name: John. YAML is more readable but whitespace-sensitive.
Use JSON for APIs and data exchange. Use YAML for config files (Docker, Kubernetes, CI/CD). YAML is more readable; JSON is more universal.
