Reduce Hash Values

Question

I am having trouble with the syntax for reduce. I have a hash of the following format:

H = {\"Key1\" => 1, \"Key2\" => 2}

I would like t

Answer 1

In case of a complex hash it might be easier to map it first to an array of values, then reduce:

values = H.map do |k, v|
    # some complex logic here
end
values.reduce(:+)

Or values.reduce(0, :+) if the array might be empty.
