We've now seen how constructor functions act as blueprints for creating objects, and how using the prototype of a constructor function lets us efficiently share methods among all objects created from that blueprint.

This is a key pattern in JavaScript for creating reusable object structures.

Okay, we've covered object creation and efficient methods... But what about inheritance with constructor functions?

What if we want to create a DeveloperPerson blueprint that inherits from our PersonConstructor blueprint? So that DeveloperPerson objects automatically has name, age, and greet, but can also have its own special developer-related properties and methods?

That's where things get a bit more involved with constructor functions, and we'll need to use a special trick called call() to make inheritance work. Let's dive into that next.
