What are mixins and interfaces in programming?

Can you explain what mixins and interfaces are in programming?

Sure! Mixins are a way to add functionality to classes without using inheritance, while interfaces define a contract that classes must follow.

Can you give me an example of a mixin?

Absolutely! In Python, a mixin could be a class that provides methods for logging. You can inherit from this mixin in other classes to add logging capabilities.

What about interfaces? How do they work?

Interfaces are used to define methods that a class must implement. For example, in Java, an interface can declare methods like draw() that any implementing class must define.

Are there any languages that don't support interfaces?

Yes, some languages like JavaScript don't have a formal interface construct, but you can achieve similar behavior using duck typing.
