+## jerryx_arg_transform_optional
+
+**Summary**
+
+The common function to deal with optional arguments. The core transform function is provided by argument `func`.
+
+**Prototype**
+
+```c
+jerry_value_t jerryx_arg_transform_optional (jerryx_arg_js_iterator_t *js_arg_iter_p,
+                                             const jerryx_arg_t *c_arg_p,
+                                             jerryx_arg_transform_func_t func);
+```
+
+ - `js_arg_iter_p` - the JS arg iterator.
+ - `c_arg_p` - the native arg.
+ - `func` - the core transform function.
+ - return value - a `jerry_value_t` representing `undefined` if all validators passed or an `Error` if a validator failed.
