Benchmark: Native filter VS Lodash omit VS custom (map & forEach)

HTML Preparation code:

<script src="https://cdn.jsdelivr.net/npm/lodash@4.17.4/lodash.min.js"></script>

Script Preparation code:

var data = [];
var omitedValues = [];
var mappedValues = [];
var dataObject = {};
var max = 1000000;
var limit = max / 2;

for (let i = 0; i < max; i ++) {
	data.push({
  	id: i,
    name: `item_${i}`
  });
  dataObject[i] = { id: i, name: `item_${i}`};
  if (i < limit) {
  	omitedValues.push(i.toString());
  }
}

const filter = data.filt

Tests:

Native filter
const filter = data.filter(item => { const name_index = item.name.split('_')[1]; return parseInt(name_index, 10) < limit; });
Lodash omit
const omitData = _.omit(dataObject, omitedValues);
Lodash omit with function
const omitByData = _.omit(data, (value, key) => { const name_index = value.name.split('_')[1]; return parseInt(name_index, 10) > limit; });
Map based
data.map(item =>{ const name_index = item.name.split('_')[1]; if (parseInt(name_index, 10) < limit) { mappedValues.push(item); } });
forEach case
data.forEach(item =>{ const name_index = item.name.split('_')[1]; if (parseInt(name_index, 10) < limit) { mappedValues.push(item); } });
