Script Preparation code:

var arr1000    = new Array(1000).fill(0).map((x) => Math.random())
var arr1000000 = new Array(1000000).fill(0).map((x) => Math.random())

var arr1000    = new Array(1000).fill(0).map((x) => Math.random())var arr1000000 = new Array(1000000).fill(0).map((x) => Math.random())​

Tests:

Array.from (1000 elements)
const valueFromArray = Array.from(arr1000)
const valueFromArray = Array.from(arr1000)
spreading (1000 elements)
const valueFromSpreading = [...arr1000]
const valueFromSpreading = [...arr1000]
Array.from (1mil elements)
const valueFromArray = Array.from(arr1000000)
const valueFromArray = Array.from(arr1000000)
spreading (1mil elements)
const valueFromSpreading = [...arr1000000]
const valueFromSpreading = [...arr1000000]
