// Modifying from https://stackoverflow.com/a/54980012/7438857 and https://stackoverflow.com/a/31936262/7438857, using a loop is more performant:

function largestNum(arr) {
  var d = data;
  var m = d[d.length - 1];
  for (var i = d.length - 1; --i > -1;) {
    if (d[i] > m) m = d[i];
  }
  return m;
}

function largestarrin2Darr(arr) {
  var maxarr = []; 

  for (var i = 0; arr.length > i; i++) {
    var arra = arr[i];
    var largest = Math.maxarr.apply(Math, arra);
    maxarr.push(largest);
  }
}
return maxarr;

console.log(largestarrin2Darr[[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]));
