How can I compare values of sets in js

Question

I have a set for which I want to compare if it contains all the values or not.

const mySet = new Set([1,2,3,4,5])

This is what I want

const isAllActive = mySet.has(1) && mySet.has(2) && mySet.has(3) && mySet.has(4) && mySet.has(5);

am sure instead of this repetition there must be some other way to check that.

Answer 1

One option is to use the every array method to see if every element in the array you're testing is in the Set .

 const mySet = new Set([1,2,3,4,5]); const hasAll = [1, 2, 3, 4, 5].every(el => mySet.has(el)); console.log(hasAll);
