Caveats

jora-cli takes a valid JSON and produce a valid JSON as a result. However, jora language could produce some values that incompatable with JSON, such values are transforming:

  • NaN, Infinity and -Infinity are converting to null, that's a behaviour of JSON.stringify()
  • undefined
    • is convering to null when a result of query (top level) or an element of an array
    • object entries with undefined as a value are eliminating
