Review Summary
Your implementation correctly handles all functional requirements—Animal class, Herbivore/Carnivore inheritance, hide/bite methods, and proper management of the static alive array. However, the _updateStatus() method violates [CHECKLIST ITEM #1] by using indexOf + splice to remove dead animals instead of the required filter method. The checklist explicitly requires: Animal.alive = Animal.alive.filter(animal => animal.health > 0). Please refactor the method to use filter for consistency with the performance guidelines.

Checklist item #1 violation: This uses indexOf + splice pattern instead of filter method. Consider using Animal.alive = Animal.alive.filter(animal => animal.health > 0) instead.

Review Summary
All requirements have been successfully implemented: the Animal base class with name and health properties, the Herbivore subclass with hidden state and hide() method, the Carnivore subclass with bite() method that properly checks both instanceof Herbivore and !target.hidden in a single condition, and the static Animal.alive array managed with the filter method as specified in the checklist. Great work on meeting all the technical constraints, including [CHECKLIST ITEM #1] using filter for dead animal removal and [CHECKLIST ITEM #2] having hide() set the state rather than toggle it.
