Ruby: How to iterate over a range, but in set increments?

ruby iterator increment

So I'm iterating over a range like so:

(1..100).each do |n|
    # n = 1
    # n = 2
    # n = 3
    # n = 4
    # n = 5
end

But what I'd like to do is iterate by 10's.

So in stead of increasing n by 1, the next n would actually be 10, then 20, 30, etc etc.

Answer

Basically you use the step() method. For example:

(10..100).step(10) do |n|
    # n = 10
    # n = 20
    # n = 30
    # ...
end
