Excellent use of network.shows :)

If you have an array where you want to do something to each element, I'd rather you limit your collection first, rather than loop over everything and selectively do something. It will lead to blocks that you can reuse and extract to methods, and it reads your intent easier.

network.shows.each do |show|
  puts show if show.day_of_week.downcase == day_of_week
end

vs

network.shows.select{ |show| show.day_of_week.downcase == day_of_week }.each do |show|
  puts show
end

...limit your collection first, rather than loop over everything and selectively do something. It will lead to blocks that you can reuse and extract to methods, and it reads your intent easier.

That makes a ton of sense. Thanks!

Would you recommend assigning network.shows.select{ |show| show.day_of_week.downcase == day_of_week } to a variable for readability? That line is 87 chars.

Yes, that would work. Or you can have a method:

def for_day_of_week(shows, day)
  shows.select{ |show| show.day.downcase == day }
end

for_day_of_week(network.shows, day_of_week).each do |show|
  puts show
end

And, we could get even fancier with the last. The naming "for_day_of_week" could be "each_day_of_week", implying we give it a block (though it is fairly advanced, and you'd only do this if you needed to re-use each_day_of_week)

def each_day_of_week(shows, day)
  shows.select{ |show| show.day.downcase == day }.each do |show|
    yield show
  end
end

each_day_of_week(network.shows, day_of_week) do |show|
  puts show
end

Dont think you need to keep this, right?
