In this chapter, we will work with more complex scenarios in which we have to use instances that belong to more than one blueprint. We will use the different features included in each of the three covered programming languages to code an application that requires the combination of multiple blueprints in a single instance. We will:
Understand how interfaces work in combination with classes
Work with multiple inheritance of classes in Python
Take advantage of abstract base classes in Python
Work with interfaces and multiple inheritance in C#
Implement interfaces in C#
Work with composition in JavaScript
