Setup

const N = 10_000;
const TEST_N = 1000;

const getStrHash = (i) => `fjklsdjflk${i}jfkladfd`; 

const intIds = Array(N).fill(null).map((_, i) => i);
const strIds = intIds.map(getStrHash);

const getRandomElem = (arr) => arr[Math.floor(Math.random()*arr.length)];

const intToValArr = intIds.reduce((arr, e) => {
	arr[e] = e + '124124124';
	return arr;
}, []);
const intToValMap = Object.fromEntries(intIds.map(e => [e, e + '124124124']));
const strToValMap = Object.fromEntries(strIds.map(e => [e, e + '124124124']));
