Script Preparation code:

var values = [{a: 30310}, {a: 100303}, {a: 3040494}, {a: 30310}, {a: 100303}, {a: 3040494}, {a: 30310}, {a: 100303}, {a: 3040494}];
var sum = 0;
var action = function(value) { if (value != null) { sum += value; } };

Tests:

for i
for (var i = 0, length = values.length; i < length; i++) { action(values[i]); }
Array.prototype.forEach
values.forEach(function (value) { action(value); });
