Tell us what’s happening:
I’ve watched the help video, read forums on how the nested for loop works, how it’s supposed to look like but when I enter the code, one I tried and then one I got from the hint I get that the product should = 0, 5040 and 54:
// running tests
multiplyAll([[1],[2],[3]])
should return
6
multiplyAll([[1,2],[3,4],[5,6,7]])
should return
5040
multiplyAll([[5,1],[0.2, 4, 0.5],[3, 9]])
should return
54
// tests completed
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*[i][j];
}
}
// Only change code above this line
return product;
}
multiplyAll([[1,2],[3,4],[5,6,7]]);
