Script Preparation code:

var handredSet = new Set(new Array(100).fill(0).map((x) => Math.random()));
var thousandsSet = new Set(new Array(10000).fill(0).map((x) => Math.random()));
var millionSet = new Set(new Array(1000000).fill(0).map((x) => Math.random()));

Tests:

Array.from (100 elements)
const valueFromArray = Array.from(handredSet)
spreading (100 elements)
const valueFromSpreading = [...handredSet]
Array.from (10k elements)
const valueFromArray = Array.from(thousandsSet)
spreading (10k elements)
const valueFromSpreading = [...thousandsSet]
Array.from (1M elements)
const valueFromArray = Array.from(millionSet)
spreading (1M elements)
const valueFromSpreading = [...millionSet]
