def total_quantity(item) do
Map.values(item.quantity_by_size)
|> Enum.sum()
end
The solution says:
I agree that reduce is a good function/concept to practice with for this solution but "best fitting" seems like a stretch. It took me a long time to understand the concept of reduce when learning functional programming and this may be a head scratcher for some folks new to Elixir and functional programming togther.
Would it be possible to change that message to say "Use the Enum.reduce function in the total_quantity function to practice."?
This doesn't give folks who can't figure out reduce right away the feeling like they are doing it "wrong".
