📚 Topic Summary
Inheritance is like family traits in programming! The `extends` keyword allows you to create a new class (a blueprint for creating objects) based on an existing class. The new class, often called a subclass or child class, inherits the properties and methods of the original class (the superclass or parent class). This saves you from writing the same code over and over again and helps keep your code organized.
Think of it like this: you might inherit your eye color from your parents. Similarly, a `Dog` class that extends an `Animal` class will automatically have properties like `name` and `age` defined in the `Animal` class, but can also have its own unique properties, like `breed`.
