Frequently Asked Questions

Does YAML support comments, while JSON does not?

Yes. YAML allows comments starting with #. This is one reason config files prefer YAML — you can document your settings inline.

Are JSON and YAML fully interchangeable?

Almost. All valid JSON is valid YAML (YAML is a superset of JSON). However, YAML supports features JSON does not, like anchors, aliases, and multi-line strings.
