Benchmark: lodash forEach vs ramda forEach vs array.forEach vs for loop

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.min.js"></script>

Script Preparation code:

var values = [];

for(i = 0; i < 10000; i++) {
    if (Math.random() > 0.5) {
      values.push({ x: true });
    } else { 
      values.push({ x: false });
    }
}

Tests:

lodash.forEach
let count = 0; _.forEach(values, v => { if (v.x) { count++; } });
array.forEach
let count = 0; values.forEach(v => { if (v.x) { count++; } });
for loop
const numValues = values.length; let count = 0; for (let i = 0; i < numValues; ++i) { if (values[i].x) { count++; } }
ramda.forEach
let count = 0; R.forEach(v => { if (v.x) { count++; } }, values);
