What is metaprogramming in Ruby?

Metaprogramming in Ruby is the ability to write code that writes code, allowing for dynamic method creation and modification.

Can you give me an example of metaprogramming in Ruby?

Sure! You can use define_method to create methods dynamically. For example:

class DynamicMethods
  define_method(:greet) do |name|
    "Hello, \\#{name}!"
  end
end

obj = DynamicMethods.new
puts obj.greet('Alice')  # Outputs: Hello, Alice!

What are the benefits of using metaprogramming?

Benefits include reducing code duplication, enhancing flexibility, and enabling the creation of domain-specific languages.

Are there any downsides to metaprogramming?

Yes, it can make code harder to read and debug, and may introduce performance overhead if not used judiciously.
