Implementation

Map()
  : super(
      methodName: "map",
      targetType: .list,
      arity: 1,
      function: (target, vm, arguments) async {
        if (arguments[0] is! ObjClosure) {
          throw RuntimeError(
            "Map function must be a function. ${arguments[0].runtimeType}",
          );
        }
        var result = [];
        for (var element in target) {
          result.add(await invokeScriptClosure(vm, arguments[0], [element]));
        }
        return result;
      },
    );
