What are the differences between methods and procs in Ruby?

In Ruby, methods are defined using the def keyword and are called with their name. Procs, on the other hand, are objects that encapsulate blocks of code and can be stored in variables.

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

Sure! Here's a simple example:

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

How do methods and procs handle arguments differently?

Methods require a specific number of arguments, while procs can accept variable numbers of arguments. If you pass too many arguments to a proc, the extra ones are ignored.

Are there any performance differences between using methods and procs?

Yes, methods are generally faster than procs because they are optimized by Ruby's interpreter. Procs have a bit more overhead since they are objects.
