Quick Ruby Array question

Rails
1

In code like:

for line_item in @cart.line_items
#Do Stuff
end

Am I guaranteed to traverse the array from the first element
successively
through each index number from first to last? If not, what’s the proper
ruby way to do that?

Thanks!

Yes, although #each is more rubyish:

@cart.line_items.each do |line_item|

do stuff

end

Thanks eden!

And if you need the indexes:

@card.line_items.each_with_index do | line_item, index |
