查找字符串中的最高和最低数字？

Question

You are given a string of space separated numbers, and have to return the highest and lowest number. I'm trying to solve this problem without using Math.max() or Math.min() .

This is my code so far:

function highAndLow(nums){  
  
  let arr = nums.split(' ');
  let maxNum = arr[0];
  let minNum = arr[0];
  
  for(let i=0; i < arr.length; i++) {
    if(arr[i] > maxNum) {
        maxNum = arr[i];
        console.log('Setting maxNum to '  + maxNum);
      }
    } 

    for(let i=0; i < arr.length; i++) {
      if(arr[i] < minNum) {
          minNum = arr[i];
          console.log('Setting minNum to '  + minNum);
       }  
    }
    const result = maxNum + " " + minNum;
    return result;
}

Expected: 542, -214 , instead got: 6, -214

Why am I getting 6 instead of 542?

The solution turns out to be easier than expected:

 function highAndLow(nums){
   var array = nums.split(' ');

  var num = array.map(item => parseFloat(item));
  var sortedArray = num.sort((a, b) =>  b -a );
  console.log(sortedArray);
  return sortedArray[0] + ', ' + sortedArray.reverse()[0]
 }

 var result = highAndLow('2 3 9 3 50 32');
 console.log(result);

In this example you don´t use neither Math.max or Math.min
