YAML vs JSON
YAML is designed to be human-readable and is widely used for configuration files (Docker, Kubernetes, Home Assistant). JSON is stricter and better for machine-to-machine data exchange (APIs, Database storage).
Key Differences
- Comments: YAML supports comments (
#), JSON does not. - Syntax: YAML uses indentation (whitespace), JSON uses braces
{}. - Strictness: YAML is more lenient with quotes, while JSON requires double quotes for all keys.
