Benchmark: lodash difference vs ES6 Set (large data set and small)

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 < 20000; i++) {
  arr1.push('' + i);
}

var arr1a = [];
for(let i = 2000; i >= 0; i--) {
  arr1a.push('' + i);
}

var arr2 = [];
for(let i = 499; i >= 0; i--) {
  arr2.push('' + i);
}

Tests:

_difference small to large
const finalArray = _.difference(arr2, arr1)
Set/Filter small to large
const outList = new Set([...arr1]); const finalArray = arr2.filter(value => !outList.has(value));
_difference small to small
const finalArray = _.difference(arr2, arr1a)
Set/Filter small to small
const outList = new Set([...arr1a]); const finalArray = arr2.filter(value => !outList.has(value));
