Script Preparation code:
const ITEMS_COUNT = 100000 function shuffleArray(array) { for (var i = array.length - 1; i >= 0; i--) { var j = Math.floor(Math.random() * (i + 1)); var temp = array[i]; array[i] = array[j]; array[j] = temp; } return array; } const ITEMS_IN_RANDOM_ORDER = shuffleArray(Array.from(Array(ITEMS_COUNT).keys()))
Tests:
[] + push
const arr = []; for (const i of ITEMS_IN_RANDOM_ORDER) { arr.push(i); }
new Array() + index insertion
const arr = new Array(ITEMS_COUNT) for (const i of ITEMS_IN_RANDOM_ORDER) { arr[i] = i }
