Why this scripts are producing different results in console? (it makes me almost crazy)
The first one returns 1; the second one 5040
function multiplyAll(arr) {
var product = 1;
// Only change code below this line
for(var i=0; i < arr.lenght; i++){
for (var j=0; j < arr[i].length; j++){
product = product * arr[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]]);```
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[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]]);
5040
