wilpam-json

it will be the json library of the hour, probably

serialization

import wilpam.json.serialize.Serializer;

// ...

void main() {
    Serializer.serialize(1.0f); // or any other object supported by Serializer
}

deserialization

import wilpam.json.deserialize.Deserializer;
import wilpam.json.obj.*;

// ...

void main() {
    JsonType jt = Deserializer.serialize("\"I'm a String\"");
}
