let snums = new Array(nums.length);
  for (let i = 0; i < nums.length; i++) {
    snums[i] = String(nums[i]);
  }
  snums.sort((a, b) => {
    let ab = a + b;
    let ba = b + a;
    return ab - ba;
  });
  let res = snums.join("");
  return res;

/**
 * 比如[3,30]这个数组,有两种排列[30,3],[3,30],将每种情况进行比较,就可以得出最小
 * @param arr
 * @returns {*}
 */

    const a_str = a + ''
    const b_str = b + ''

  }).join('')
}

console.log(sortArrToStr([3, 30]))
