But that's not all yet. But that's not all yet.
Even after the fix, there's still important difference in `"class Rabbit extends Object"` versus `class Rabbit`. Even after the fix, there's still an important difference between `"class Rabbit extends Object"` and `class Rabbit`.
As we know, the "extends" syntax sets up two prototypes: As we know, the "extends" syntax sets up two prototypes:
1. Between `"prototype"` of the constructor functions (for methods). 1. Between `"prototype"` of the constructor functions (for methods).
2. Between the constructor functions themselves (for static methods). 2. Between the constructor functions themselves (for static methods).
In our case, for `class Rabbit extends Object` it means: In the case of `class Rabbit extends Object` it means:

By the way, `Function.prototype` has "generic" function methods, like `call`, `bind` etc. They are ultimately available in both cases, because for the built-in `Object` constructor, `Object.__proto__ === Function.prototype`.
