Tell us what’s happening:

Your code so far


function largestOfFour(arr) {
  // You can do this!
  var max;
  var newArray = [];
  for(var i = 0; i < 4; i++){
    max = 0;
    for(var j = 0; j < 4; j++){
      if(arr[i][j] > max)
        max = arr[i][j];
    }
  
    newArray[i] = max;
  }
  console.log(newArray);
  return arr;
}

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

Link to the challenge:

What am I doing wrong ? I see correct results but it still says it’s wrong.

You see newArray in the console but the function is returning arr, the array inputted in the function and not changed

The value that matters is what the function returns, in practice your function is not doing anything because it does return that array immutated

I’m dumb. Thank you sir.
