How to determine if an Local<Object> is Error? 如何判断Local<Object>是否为Error

[Jasonzyt]

I used isInstanceOf<T>, but idk what T is

[LanderlYoung]

use Local::instanceOf
with the parameter be the js Error reference

[Jasonzyt]

那lua的error呢

伪代码

Local<Object> obj;
auto error = engine->get("Error");
auto isError = obj.instanceOf(error);
