Can anyone please help to find out error of this code
Your code so far

function multiplyAll(arr) {
  let product = 1;
  let sum="";
  // Only change code below this line
for (let i= 0; i < arr.length; i++) {
  for(let j= 0; j< arr[i].length; j++) {
    sum = product* arr[i][j];

Link to the challenge:

Your main issue is that you are adding lines of code outside of the " Only change code below this line" areas.

You don’t need the let sum=""; and you shouldn’t be returning sum.

Your goal is to return the product of all of the numbers.
So a variable called sum wouldn’t make sense in this context.

once you fix those things, then it will pass
