Go through array with for loop

Tell us what’s happening:

Hi !
I extracted a few steps to do the challenge “Return Largest Numbers in Arrays”.
The first step is to sort the arrays.

I am using a for loop to go through all the arrays but it seems that it only sorts the first one.

Can you help me identify the issue here?

Thanks a million!

Your code so far

function largestOfFour(arr) {
  // You can do this!
  var arrayLength = arr.length;
  for (var i = 0; i < arrayLength ; i++ ){
  arr[i].sort(function(a,b){return(a - b);});
  return arr[i];

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);```

Hi @mrclasse

You’re only returning the first element of the array to the function. The challenge wants the entire array, after sorting, to be returned.

Yep, that’s the issue. I probably need to reach the array inside the first one.
