I’m trying to understand some details of the following statement:

constructor is a pre-defined [[DontEnum]] property of the object pointed to by the prototype property of a function object and will initially point to the function object itself.

Intuitively, I was trying to rephrase it like this:

Every function object has a prototype property that points to a special object by default. The object has a constructor property (a pre-defined [[DontEnum]] property), which points back to the function object.

But I was told this was wrong. Why? Is it only because we can directly set it to null after creation?
