Script Preparation code:
var testSet = new Set(); for (let i = 1; i <= 100000; i++) { testSet.add(i); }
Tests:
Array.from()
const arrayFrom = Array.from(testSet.values());
spread operator
const arraySpread = [...testSet];
for...of loop
const arrayForOf = []; for (const value of testSet) { arrayForOf.push(value); }
iterator.next()
const arrayWhileNext = []; let iterator = testSet.values(); let next = iterator.next(); while (!next.done) { arrayWhileNext.push(next.value); next = iterator.next(); }
