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)
Array intersection 1
first.filter((f) => second.includes(f))
Array intersection 2
second.filter((f) => first.includes(f))
