Getting the sum of a collection (all models) with backbone.js

Question

I\'m just learning backbone. I have the following

window.ServerList = Backbone.Collection.extend({

    model: Server,

    cpuTotal: function(){
        if          


        

Answer 1

Here is the best way I know how:

cpuTotal: function() {
    return this.reduce(function(memo, value) { return memo + value.get("cpu") }, 0);
}

Here is a jsFiddle of the solution.
