如何避免在使用Math.random时获得两个相同的数组？

const seed = new Date().getTime().toString();
const randomArray1 = generateRandomArray(seed);
const randomArray2 = generateRandomArray(seed + '1');

function shuffleArray(array) {
  for (let i = array.length - 1; i > 0; i--) {
    const j = Math.floor(Math.random() * (i + 1));
    [array[i], array[j]] = [array[j], array[i]];
  }
  return array;
}

const randomArray1 = shuffleArray([1, 2, 3, 4, 5]);
const randomArray2 = shuffleArray([6, 7, 8, 9, 10]);

const crypto = require('crypto');
const randomArray1 = generateRandomArray(crypto.randomBytes(32).toString('hex'));
const randomArray2 = generateRandomArray(crypto.randomBytes(32).toString('hex'));
