How to convert Scala Map into JSON String?

Question

For example, I have this Map value in Scala:

val m = Map(
    \"name\" -> \"john doe\", 
    \"age\" -> 18, 
    \"hasChild\" -> true, 
    \"childs\" -

If you're working with a well-defined data model, why not define case classes and use Play JSON macros to handle conversion? i.e.

case class Person(name: String, age: Int, hasChild: Boolean, childs: List[Person])

implicit val fmt = Json.format[Person]

val person = Person(...)

val jsonStr = Json.toJson(person)
