How do I use procs in Ruby?

Procs in Ruby are objects that encapsulate blocks of code. You can create a proc using Proc.new or the -> syntax.

Can you show me an example of creating and using a proc?

Sure! Here's a simple example:

my_proc = Proc.new { |x| x * 2 }
puts my_proc.call(5)  # Output: 10

What’s the difference between a proc and a lambda?

The main difference is that lambdas check the number of arguments, while procs do not. A lambda will raise an error if the wrong number of arguments is passed.

Can I use procs as method arguments?

Yes, you can pass procs as arguments to methods, allowing for flexible and reusable code.
