Explanation:

* Object.prototype.constructor

Returnsa reference to the Object function that created the instances prototype. Note that the value of this property is a reference to the function itself, not a string containing the functions name. The value is only read-only for primitive values such as 1,true and -test-.

* The constructor property is created together with the function as a single property of func.prototype.
