Herbivores and Сarnivores

Nature is well suited to reflect the principles of Object Oriented Programming. All instances of the Animal class must have health and a name. Health is 100 by default.

Create a Herbivore class. Herbivore has a method of hide, which changes the hidden property of the beast to the opposite value and helps to hide from carnivores.

Create a Сarnivore class. Carnivore has a bite method, which takes a herbivore object and decreases the object's health by 50. The method does not work if it is another сarnivore, or the herbivore is currently hiding.

Herbivore and Сarnivore should extend an Animal class.

All alive animals should be in the static Animal.alive array. If the health of the animal reaches 0, the beast dies and it should be removed from the static array Animals.alive.

Example:

const deer = new Herbivore('Bembi');
const panther = new Carnivore('Bagira');
const lion = new Carnivore('King');
const rabbit = new Herbivore('Max');

Animal.alive === [
  {name: 'Bembi', health: 100, hidden: false},
  {name: 'Bagira', health: 100},
  {name: 'King', health: 100},
  {name: 'Max', health: 100, hidden: false},
];

lion.bite(deer);
panther.bite(lion);
Animal.alive === [
  {name: 'Bembi', health: 50},
  {name: 'Bagira', health: 100},
  {name: 'King', health: 100},
  {name: 'Max', health: 100},
];

panther.bite(deer);
rabbit.hide();
panther.bite(rabbit);

Animal.alive === [
  {name: 'Bagira', health: 100},
  {name: 'King', health: 100},
  {name: 'Max', health: 100, hidden: true},
];
