#1

Tell us what’s happening:

Your code so far


function largestOfFour(arr) {
  // You can do this!
  var answer = [];
  for ( var i = 0; i < arr.length; i++) {
     var biggestNumber = 0;
     for ( var j = 0; j < arr[i].length; j++) {
      if (arr[i][j] > biggestNumber) {
        biggestNumber = arr[i][j];
      }
    }
    answer[i] = biggestNumber;
  }
  return arr[i][j];
}

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

So close! You have all the logic correct but check one more time what you are returning.

You are saving numbers into somewhere else.

You have an other thing to consider… what happens when the biggest number is negative?
