Return Largest Numbers in Arrays confused about subarrays

Programming
1

Tell us what’s happening: I understand how to solve this problem if we are just looping through one array but I dont really understand how to do when we add the other 3 sub arrays in.

Right now my code returns: [4, 5, 5, 5,]

Your code so far


function largestOfFour(arr) {
  // You can do this!
  var result = [];
  var largeNum = 0;
  for (var i = 0; i < arr.length; i++) {
    for (var j = 0; j < 4; j++) {
      if (arr[i][j] > largeNum) {
      largeNum = arr[i][j];
      }
    result.push(largeNum);
    }
    return result;
  }
}

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

Okay that you for clearing that up!

I moved the return out of the for loops and put the largeNum var inside the outer loop and now what im getting to return is [4,5,13,27,32,35,37,39,1000,1001]

Of course! Thank you so much for your help!
