SecondHighLow

SecondHighLow

function SecondGreatLow(arr) { 
  arr = arr.sort(function (a, b) {return a - b});
  return secondLow(arr) + " " + secondHigh(arr);
       
}

function secondLow(arr) {
  for (var i = 0; i < arr.length; i++)
    if (arr[i] !== arr[i +1])
      return (arr[i + 1]);
}

function secondHigh(arr) {
  for (var i = arr.length - 1; i > 0; i--)
    if (arr[i] !== arr[i - 1])
      return (arr[i - 1]);
}

console.log(SecondGreatLow([1, 42, 42, 180]));

So this code does not work, but when I add a semicolon to the end of line 14 it does work. I can't figure out why.
