When using array.each_with_index how do you start at a desired index
position?

I can do it like this, but its not very clean and doesnt seem efficient
:

desired_index_start = 20
array.each_with_index do |value,index|
  next if index<desired_index_start
end

Thanks
Chris

Here's one way.

array[20..-1].each_with_index do |value,index|
  ...
end
