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 *=[i][j]
}
}
// Only change code above this line
return product;
}

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