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));

var firstSet = new Set(first);
var secondSet = new Set(second);

Tests:

Javascript Set intersection (larger set first)
new Set(first.filter(item => secondSet.has(item)));
Lodash intersection
_.intersection(first, second)
Javascript Array intersection
first.filter(it => second.includes(it))
Javascript Set intersection (new feature) (larger set first)
firstSet.intersection(secondSet)
Javascript Set intersection (smaller set first)
new Set(second.filter(item => firstSet.has(item)));
Javascript Set intersection (new feature) (smaller set first)
secondSet.intersection(firstSet)
Javascript Set intersection (new feature) (smaller set first) (with set init time)
const newFirstSet = new Set(first); const newSecondSet = new Set(second); newFirstSet.intersection(newSecondSet)
