    ExecutionContext* executionContext) const {
  v8::Local<v8::Value> iteratorGetter;
  if (!getInternal(v8::Symbol::GetIterator(m_isolate), iteratorGetter) ||
      !iteratorGetter->IsFunction())
    return nullptr;

                  v8::Local<v8::Function>::Cast(iteratorGetter),
                  executionContext, m_dictionaryObject, 0, nullptr, m_isolate),
