Benchmark: Array Intersection vs. Lodash part 3 vs. Native Set Intersection Optimized

HTML Preparation code:

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

Script Preparation code:

var first = [...Array(100)].map(it => ~~(Math.random() * 1000));
var second = [...Array(20)].map(it => ~~(Math.random() * 1000));
const firstSet = new Set(first);
const secondSet = new Set(second);

Tests:

Lodash intersection
_.intersection(first, second)
Javascript Array intersection
first.filter(it => second.includes(it))
Native Set intersection
firstSet.intersection(secondSet);
