<script src="https://cdn.jsdelivr.net/npm/immutability-helper@2.7.0/index.min.js"></script>

Tests:

Immutable.Set union
const set1_Immutable = new Immutable.Set(Array.from(Array(100).keys())); const set2_Immutable = new Immutable.Set(Array.from(Array(1000).keys())); const result = set1_Immutable.union(set2_Immutable)
Convert JS Set to array, construct new Set
const set1_JS = new Set(Array.from(Array(100).keys())); const set2_JS = new Set(Array.from(Array(1000).keys())); const result = new Set([...set1_JS, ...set2_JS])
Array.from, construct new Set
const set1_JS = new Set(Array.from(Array(100).keys())); const set2_JS = new Set(Array.from(Array(1000).keys())); const result = new Set(Array.from(set1_JS).concat(Array.from(set2_JS)))
