Benchmark: for...in vs _.values().map

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.core.js"></script>

Script Preparation code:

function generateObject(objectSize) {
    let obj = {};
    for (let i = 0; i < objectSize; i++) {
        obj['key' + i] = 'val' + i;
    }
    return obj;
}

Tests:

for...in
const obj = generateObject(100000) const arr = [] let flag = true for (const f in obj) { if (flag) { arr.push(obj[f]) } }
_.values.map
const obj = generateObject(100000) let flag = true _.values(obj).filter(v => flag ? v : null)
