Script Preparation code:

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

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)
Javascript Array intersection
first.filter(it => second.includes(it))
