If anyone has a good idea for this api let me know, Something like what i propose below might work well:

module JsonSearch

enum SearchError {
  ExpectedGetProperyOnObject,
  PropertyNotFound
}

getProperty(json: Json, property: string) => Result<Json, SearchError>
getPropeties(json: Json) => Result<string[], SearchError> // this could give an Err(ExpectedGetProperyOnObject)

If this is what the api looks like though it would probably be best to add this as a submodule. would love to hear some alternative ideas to the api I suggested above though, especially as the above doesnt make it easy to get nested props.
