A simple convenience function for adding together an array of numbers.
//
// Iterates over an array of numbers and returns the sum. Example:
//
// _.sum([1, 2, 3]) => 6
//
_.sum = function(obj) {
if (!$.isArray(obj) || obj.length == 0) return 0;
return _.reduce(obj, function(sum, n) {
return sum += n;
});
}
