for in w/ arrays

My God, please never use `for (var i in array) { ... array[i] ... }`.

Alternatives:

```
// Instead of
for (var i in array) {
    console.log(array[i]);
}
// PLEASE use
for (var i = 0; i < array.length; i ++) {
    console.log(array[i]);
}
// or
array.forEach(function (e) {
    console.log(e);
});
```
