What are the differences between mixins and inheritance?

Mixins and inheritance are both ways to share code in object-oriented programming, but they work differently. Inheritance creates a parent-child relationship, where a child class inherits properties and methods from a parent class. Mixins, on the other hand, allow you to add functionality to classes without forming a strict hierarchy.

Can you give me an example of each?

Sure! Inheritance example: a Vehicle class that has properties like speed and fuel, and a Car class that inherits from Vehicle. A mixin example: a Flyable mixin that adds a fly method to any class, like Bird or Airplane, without needing a common ancestor.

What are the advantages of using mixins?

Mixins promote code reusability and flexibility. They allow you to compose classes with different functionalities without being tied to a single inheritance chain, making it easier to manage and extend your code.

Are there any downsides to using mixins?

Yes, mixins can lead to complexity and confusion if overused. They can create a situation known as the "diamond problem" where multiple mixins provide the same method, leading to ambiguity about which method to use.
