Benchmark: Test lodash difference

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 < 100000; i++) {
  arr1.push('' + i);
}

var arr2 = [];
for(let i = 100001; i >= 200000; i--) {
  arr2.push('' + i);
}

Tests:

Spread lodash
const combo = [..._.difference(arr2, arr1), ..._.difference(arr1, arr2)];
Concat lodash
const combo = _.difference(arr2, arr1).concat(_.difference(arr1, arr2));
ES2024 set symmetricDifference
const set1 = new Set(arr1); const set2 = new Set(arr2); const combo = set1.symmetricDifference(set2)
