HTML Preparation code:

<script src="https://cdn.jsdelivr.net/lodash/4.16.0/lodash.min.js"></script>

Script Preparation code:

var values = [{a: 30310}, {b: 100303}, {c: 3040494}]

Tests:

lodash.forEach
var count = 0; _.forEach(values, function(v,i) { if (v.a != null) { count++; } });
native
var count = 0; for (var i = 0; i < values.length; i++) { if (values[i].a != null) { count++; } }
ES5 forEach (cannot break;)
var count = 0; values.forEach(function(v,i) { if (v.a != null) { count++; } });
ES5 for-in
var count = 0; for (value in values) { if (value.a != null) { count++; } }
ES6 for-of
var count = 0; for (value of values) { if (value.a != null) { count++; } }
