Need help return largest number in array challenge

1

hello people.
Any idea why this code is returning for return largest number in array challenge

  [27,0,39,1001]

instead of

[27,5,39,1001]

function largestOfFour(arr) {
   var numberaccessed=0;
  var bigarray=[];
  var numberaccessedarr;
  for(i=0;i<arr.length;i++){ 
    numberaccessedarr=0;
    for(j=0;j<arr[i].length;j++){

      if(numberaccessed<arr[i][j]){
        numberaccessed=arr[i][j];
        numberaccessedarr=numberaccessed;
      }

    }

    bigarray=bigarray.concat(numberaccessedarr);
  }
  return bigarray;
}
largestOfFour([[13, 27, 18, 26], [4, 5, 1, 3], [32, 35, 37, 39], [1000, 1001, 857, 1]]);

for the algorithm challenge return largest number in array
EDIT: Got solved at gitter
had to reinitialise numberaccessed too…

Maybe look into sort(). Will do most of your heavy lifting.

Hello there.
on the second line just define variable, don’t set it to 0.var numberaccessed;
set it to zero on 6th line numberaccessedarr=0;numberaccessed=0;
