Objects inherit from objects

All of the examples so far in this chapter assume that you create your objects with constructor functions and you want objects created with one constructor to inherit properties that come from another constructor. However, you can also create objects without the help of a constructor function, just by using the object literal and this is, in fact, less typing. So how about inheriting those?

In Java or PHP, you define classes and have them inherit from other classes. That's why you'll see the term classical, because the OO functionality comes from the use of classes. In JavaScript, there are no classes, so programmers that come from a classical background resort to constructor functions because constructors are the closest to what they are used to. In addition, JavaScript provides the new operator, which can further suggest that JavaScript is like Java. The truth is that, in the end, it all comes down to objects. The first example in this chapter used this syntax...
