我如何避免从两个不同的随机变量中获得相同的值，但这些值来自相同的列表？

function shuffle(array) {
  let currentIndex = array.length, temporaryValue, randomIndex;

  // While there remain elements to shuffle...
  while (0 !== currentIndex) {

    // Pick a remaining element...
    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex -= 1;

    // And swap it with the current element.
    temporaryValue = array[currentIndex];
    array[currentIndex] = array[randomIndex];
    array[randomIndex] = temporaryValue;
  }

  return array;
}

const values = [1, 2, 3, 4, 5];
const shuffledValues = shuffle(values);

const randomVariable1 = shuffledValues[0];
const randomVariable2 = shuffledValues[1];

const values = [1, 2, 3, 4, 5];
const randomVariable1 = Math.floor(Math.random() * values.length);
const randomVariable2 = Math.floor(Math.random() * values.length);

while (randomVariable1 === randomVariable2) {
  randomVariable2 = Math.floor(Math.random() * values.length);
}

const uniqueValues = new Set([values[randomVariable1], values[randomVariable2]]);

function getRandomValues(values, count = 2) {
  if (count === 1) {
    return values[Math.floor(Math.random() * values.length)];
  }

  const randomIndex = Math.floor(Math.random() * values.length);
  const randomValue = values[randomIndex];

  const remainingValues = values.filter((_, index) => index !== randomIndex);
  const nextRandomValue = getRandomValues(remainingValues, count - 1);

  return [randomValue, ...nextRandomValue];
}

const values = [1, 2, 3, 4, 5];
const [randomVariable1, randomVariable2] = getRandomValues(values);
