JS创建具有唯一随机数的数组

function createUniqueRandomArray(length) {
  var uniqueRandomArray = [];
  var generatedNumbers = {};

  while (uniqueRandomArray.length < length) {
    var randomNum = Math.floor(Math.random() * length);

    if (!generatedNumbers[randomNum]) {
      generatedNumbers[randomNum] = true;
      uniqueRandomArray.push(randomNum);
    }
  }

  return uniqueRandomArray;
}

var result = createUniqueRandomArray(10);
console.log(result);
