Factory & Constructor Functions

What issue might arise with this constructor chain?

function Animal(name) {
  this.name = name;
}

function Dog(name, breed) {
  Animal(name);
  this.breed = breed;
}

const dog = new Dog('Rex', 'German Shepherd');
console.log(dog.name);

The code will throw an error
dog.name will be undefined
The name property will be undefined because Animal is called as a regular function, not as a constructor. When Animal(name) is called, 'this' inside Animal refers to the global object, not the new Dog instance. To fix this, use Animal.call(this, name) to properly set the context of 'this' in the Animal constructor. This is a common mistake when attempting to chain constructor functions without properly binding 'this'.
The breed will be incorrect
There is no issue
