Maps 🔗

Map[String, T] work as you expect.

            Map(
    "a" -> 5,
    "b" -> 123
).toJson
// {"a":5,"b":123}

          

            """ {"a":5,"b":123} """.parseJson[Map[String, Int]]
// Map(a -> 5, b -> 123)

          

Maps are limited in the sense that the values have to be of same type.
If you need them different, consider using case classes or dynamic JSON values.
