 That's because the child constructormust call `super()`.
 Eso es porque el constructorhijo debe llamar a `super()`.

 Here's the corrected code:
 Aqui el código corregido:

 Here's the code with`Rabbit`extending `Animal`.
 Aquí está el código de la clase`Rabbit`que extiende a `Animal`.

 Unfortunately,`Rabbit`objects can't be created. What's wrong? Fix it.

 #Extended clock
 #Reloj extendido

 We've got a `Clock` class. As of now, it prints the time every second.
 Tenemos una clase de 'Clock'. A partir de ahora, imprime la hora cada segundo.


 [js src="source.view/clock.js"]

 Create a new class `ExtendedClock`that inherits from `Clock`and adds the parameter `precision` -- the number of `ms` between "ticks".Should be `1000` (1second) by default.
 Crea una nueva clase `ExtendedClock`que herede de `Clock`y agrega el parámetro `precision`: este es el número de `milisegundos` entre "tics".Debe ser `1000` (1segundo) por defecto.

 -Your code should be in the file `extended-clock.js`
 -Don't modify the original`clock.js`. Extend it.
 -Tu código debe estar en el archivo `extended-clock.js`
 -No modifiques el`clock.js` original. Extiéndelo.
