use " to surround value.tostring

if value is a datetime object, JSONValue.toJSONString({"now": datetimeinstance}) will get invalid json string.

json maps are for primitive values only. the are for serialization not storing date objects to and from the disk directly getting stored into the json that simply doesn't happen.

this issue should get closed as invalid. inputting an object that isn't primitive into a json should result in object.toString() when storing it in memory and nothing more. You found an issue that I also ran into but, it's not the one you think it was

@jredfox I think I do the right thing. If the object is not int/float/bool/null/map/array/... , it should call toString() and be surrounded by double quote.

no because then everything is a string and if everything is a string then it's not a parser it's a string. Suggestion close issue. Your format is invalid json and still wouldn't support what you wanted. That would be something like gjson which isn't this library it's json only and by the way it's not double quotes either it needs to parse the entire object to and from json
