Benchmark: Lodash vs. Set Intersection test123

HTML Preparation code:

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

Script Preparation code:

const generateRandomArray = (size = 1000, min = 1, max = 1000) =>
  Array.from({ length: size }, () =>
    Math.floor(Math.random() * (max - min + 1)) + min
  );

var first = generateRandomArray();
var second = generateRandomArray();

Tests:

Javascript Set intersection
const firstSet = new Set(first); const secondSet = new Set(second); new Set([...firstSet].filter(item => secondSet.has(item)));
Lodash intersection
_.intersection(first, second)
