Every Object is a function and every function is Object – Which is Correct?

by

  1. Anything that is not a primitive type (undefined, null, number, string, boolean) is an object (or an instance) in JavaScript. That means function inherits from object.

  2. Object instances can contain more instances which can be functions. That’s what we call a “method” (since it has an automatic this variable).

  3. Since you can’t “call” every Object instance, not every object is a function.
