Benchmark: Lodash forOwn vs Native keys + forEach 1000 keys

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 = Object.assign({}, _.range(1000).map((i) => ({
  status: `status_${i}`,
  statusDateneingang: `statusDateneingang_${i}`,
})));

Tests:

lodash forOwn
_.forOwn(obj, (a) => {console.log(a)});
Keys and then forEach
Object.keys(obj).forEach((a) => {console.log(a)});
for key
for (let key in obj) { // check if the property/key is defined in the object itself, not in parent if (obj.hasOwnProperty(key)) { console.log(key, obj[key]); } }
for key value
for (const [key, value] of Object.entries(obj)) { console.log(key, value); }
