Tell us what’s happening:

why is that i am not getting the output

Your code so far

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

// Modify values below to test your code
multiplyAll([[1,2],[3,4],[5,6,7]]);

This will return a subarray, bu you want to access index j from a subarray.
