How to sum property values of an object?

Question

I want to sum the property values of PieData. My expected output is 25515512+916952499 = 942468011

Answer 1

var PieData = [{
        value: 25515512,
        color: "#00a65a",
        highlight: "#00a65a",
        label: "Received Fund"
    }, {
        value: 916952499,
        color: "#f56954",
        highlight: "#f56954",
        label: "Pending Fund"
    }],
    userSelectedColors = ['value'];

var totalCount = _.sumBy(userSelectedColors, _.partial(_.sumBy, PieData));

console.log(totalCount);
