    Simple Prune for simple path and only JsObject

  42. def read[T](t: T): Reads[T]

    Pure Reads doesn't read anything but creates a JsObject based on JsPath with the given T value

  43. def read[T](implicit r: Reads[T]): Reads[T]

    Reads a T at JsPath

  44. def readNullable[T](implicit r: Reads[T]): Reads[Option[T]]

    Reads a Option[T] search optional or nullable field at JsPath (field not found or null is None and other cases are Error).

    Reads a Option[T] search optional or nullable field at JsPath (field not found or null is None and other cases are Error).

    It runs through JsValue following all JsPath nodes on JsValue: - If any node in JsPath is not found => returns None - If any node in JsPath is found with value "null" => returns None - If the entire path is found => applies implicit Reads[T]

    Reads an Option[T] search optional or nullable field at JsPath (field not found replaced by default value, null is None and other cases are Error).

    It runs through JsValue following all JsPath nodes on JsValue except last node: - If any node in JsPath is not found => returns default value - If any node in JsPath is found with value "null" => returns None - If the entire path is found => applies implicit Reads[T]

  46. def readWithDefault[T](defaultValue: => T)(implicit r: Reads[T]): Reads[T]

    Reads a T at JsPath
