How can I use procs effectively in Ruby?

Procs in Ruby are blocks of code that can be stored in variables. They allow for flexible and reusable code. What specific use case do you have in mind?

I want to use procs for callbacks in my application. How can I implement that?

You can define a proc and pass it as a callback to methods. For example, you can create a method that accepts a proc as an argument and calls it when needed.

Can you show me a code example?

Sure! Here's a simple example:

callback = Proc.new { |x| puts "Callback called with #{x}" }

def execute_callback(proc)
  proc.call(42)
end

execute_callback(callback)

That makes sense! Are there any performance considerations I should be aware of?

Yes, while procs are powerful, they can introduce overhead if used excessively. It's best to use them judiciously.
