Options for processing X elements of an array at a time using Ruby

Question

We want to process 1000 elements of an array at a time. What are the options for doing this in Ruby?

Obviously, one approach is to do a simple loop and slice 1000 elemen

Answer 1

We wound up using each_slice:

array = [1,2,3,4,5,6,7,8,9,10]
array.each_slice(3) do |group| 
  puts group
end

Answer 2

In Rails you can use in_groups_of:

array = [1,2,3,4,5,6,7,8,9,10]
array.in_groups_of(3, false).each do |group| 
  puts group
end

# => [[1, 2, 3], [4, 5, 6], [7, 8, 9], [10]]
