JavaScript函数的正确类型是什么？

Question

Most people know that all functions in JavaScript are actually objects, but why is it that typeof function() {} returns function instead of object ? By this logic, why does typeof [] not return array ?

Is this just a 'standard' that is followed or is there a valid reason?

Answer 1

Because that's what the spec says.

typeof returns primitive types only; all regular objects are reported as "object" .
