Hi all

Is there a method to iterate over an array with the index? Something  
like

my\_array.each\_with\_index do |obj, index|  
…  
end

Just couldn’t find such a method… maybe I worked too much today… 😉

Thanks  
Josh

Won’t each\_with\_index suffice?

Hi Josh,

I agree that you worked too much today. Ruby’s Enumerable class has that  
exact method.
