What are decorators in Ruby?

Decorators in Ruby are design patterns that allow you to modify the behavior of a method or class without changing its code.

Can you give me an example of how to use a decorator?

Sure! Here's a simple example:

def my_decorator
  puts 'Before the method'
  yield
  puts 'After the method'
end

my_decorator { puts 'Inside the method' }

This will output:

Before the method
Inside the method
After the method

What are some common use cases for decorators?

Common use cases include logging, access control, and caching. They help keep your code clean and maintainable.

Are there any built-in decorators in Ruby?

Ruby doesn't have built-in decorators like Python, but you can easily create your own using methods or modules.
