is there a cleaner way to do an each but only if the array exists

Raw

if array do each

	if array
	array.each do \| elm \|
	elm.doing_stuff
	end
	end

If you're in Rails, this should work:

array.try(:each) do |elm|
  elm.doing_stuff
end

miah commented May 28, 2014

array.each { |elm| elm.doing.stuff } if array

Another approach:

array.each do |elm|
  elm.doing_stuff
end if array
