Contract

  1. YAML.parse parses a basic YAML key-value mapping to a JavaScript object
  2. YAML.parse parses nested mappings and sequences into nested objects and arrays
  3. YAML.parse correctly parses scalar types including numbers, booleans, and null
  4. YAML.parse parses custom options such as reviver function
