Benchmark: Loop over object: lodash.forOwn vs Object.keys().forEach

HTML Preparation code:

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

Script Preparation code:

var obj = Array.from({ length: 1000 }).map((value, i) => i).reduce((val, v) => { val[v] = v; return val; }, {})

Tests:

lodash.each
_.each(obj, function(v, k) { console.log(v, k); });
lodash.forOwn
_.forOwn(obj, function(v, k) { console.log(v, k); });
Object.keys().forEach
Object.keys(obj).forEach(function (k) { let v = obj[k]; console.log(v, k); });
for..in
for (const k in obj) { if (obj.hasOwnProperty(k)) { let v = obj[k]; console.log(v, k); } }
