— Yeah


But that's kind of bad practice in languages with duck-typing, since it means you can't easily subclass/add behaviour

— Or instanceof or isPrototypeOf

— Complex duck typing can also validate functions, I think

— But that's more unit-testy and less production

— Well, instanceof would still work in JS:

class MyError extends SyntaxError {
new TypeError() instanceof Error // true
new MyError() instanceof Error // true
