If you don't know what lambdas are, don't worry, there is a full chapter dedicated to them. If you have been using a functional language already, you will find functional language-like constructs supported in Kotlin.

You can view each object as a minicomputer on its own: it has a state and can perform actions. An object through its available actions exhibits some sort of behavior; therefore, there is a clear analogy between objects/entities and real life.
