adding up a total using jade template engine

Question

I need to add up a total for a shopping basket but I dont know how to do this using jade

Here is how I thought I could implement it but it doesnt work, other ways I have tried just keep throwing errors.

Does anyone know how I would do this?

each item in bagItems
    - var total = total + item.realprice
p= total

Answer 1

This should be pretty easy to do using the reduce method on your array.

p= bagItems.reduce(function(total, item) { return total + item.realprice; }, 0)
