Title
Body
I have an array of items like so: @items = [ {price: 12, quantity:1}, {price: 4, quantity:1}, {price: 8, quantity:1} ] And I am looking for something like this: sumPrice: -> @items.sum (item) -> item.price * item.quantity Or anything as close as possible to this, that makes it super-easy for everyone reading the code to understand whats happening. So far I came up with: sumPrice: -> (items.map (a) -> a.price * a.quantity).reduce (a, b) -> a + b contains too much functional magic loses descriptiveness And: sumPrice: -> sum = 0 for item in items sum += item.price * item.quantity sum which can be understood by novice JS/Coffee programmers feels a bit stupid I love CoffeeScript so I hope there is a nicer solution to this & similar scenarios that I miss.
