Benchmark: Lodash difference vs Some & Filter

HTML Preparation code:

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

Script Preparation code:

var arr1 = [];
for(let i = 0; i < 100; i++) {
  arr1.push('' + i);
}

var arr2 = [];
for(let i = 49; i >= 0; i--) {
  arr2.push('' + i);
}

Tests:

Lodash
const notInArr1 = _.difference(arr2, arr1) const notInArr2 = _.difference(arr1, arr2)
Set & Filter
const notInArr1 = arr2.filter(value => !arr1.some(v => v === value)); const notInArr2 = arr1.filter(value => !arr2.some(v => v === value));
