apropo:

[1] pry(main)> (1..10).to_a.select(&:odd?)
=> [1, 3, 5, 7, 9]
[2] pry(main)> (1..10).to_a.reject(&:odd?)
=> [2, 4, 6, 8, 10]

Super tare! Exista functie pentru aproape orice 😆. Si devine mai frumos items.reject(&:done?) si items.select(&:done?)

def find_by_description(description)
items.find {|e| e.description == description}
end
def set_as_done(description)
item = self.find_by_description(description)
if item
item.done!
else
false
end
end
