Frequently asked questions

When should I use YAML vs JSON?

YAML is human-friendly and great for configs. JSON is compact and ideal for APIs and machine-to-machine communication.

Does it support YAML anchors and aliases?

Yes, the underlying parser handles standard YAML 1.2 features including anchors, references, and multi-document streams.

What about comments?

YAML comments are preserved when round-tripping YAML to YAML, but they are lost when converted to JSON, which has no comment syntax.
