napi has named property

napi_status napi_has_named_property(napi_env env,
                                    napi_value object,
                                    const char* utf8Name,
                                    bool* result);

• [in] env: The environment that the N-API call is invoked under.
• [in] object: The object to query.
• [in] utf8Name: The name of the property whose existence to check.
• [out] result: Whether the property exists on the object or not.

Returns napi_ok if the API succeeded.

This method is equivalent to calling [napi_has_property][] with a napi_value created from the string passed in as utf8Name.
