Answer 1

function randomArrByNum(num, min, max) {
  return Array(num).fill(null).map(() => Math.floor(Math.random() * (max - min + 1) + min));
}

function sortByOrder() {
  let arr = randomArrByNum(10, 1, 20);
  arr.sort((a, v) => a - v);
  console.log(arr);
  let temp = [], result = [];
  while (arr.length > 0) {
    const cur = arr.shift();
    if (temp.length === 0) {
      temp.push(cur);
      continue;
    }
    if (cur - temp[temp.length - 1] > 1) {
      result.push(temp);
      temp = [];
      temp.push(cur);
    } else {
      temp.push(cur);
    }
  }
  if (temp.length !== 0) result.push(temp);
  return result;
}
