Tell us what’s happening:
Why it worked 2 out of 4 tests. Tell me where I’m wrong .
Thanks for answering me

Your code so far

function largestOfFour(arr) {
var largestNum=-Infinity;
var resultArr=[];>{
  for(var i=0; i<subArr.length; i++){
return (resultArr)

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

Challenge: Return Largest Numbers in Arrays

Link to the challenge:

You have two related things here.

  1. I wouldn’t use -Infinity. There is a better choice of inital value for each subarray

  2. You never reset largestNum in between subarrays
