JsNothing

object JsNothing extends JsValue with Product with Serializable

It's a special Json value that represents 'nothing'. Inserting nothing in a json leaves the json unchanged. Functions that return a JsValue, return JsNothing when no element is found, what makes them total on their arguments.

val obj = JsObj.empty obj("a") == JsNothing obj.inserted("a",JsNothing) == obj
