sorry if this question seems a little stupid but I have the following code:

```
var sides = {
    'red': [0,0,0,0,0,0,0,0,0],
    'ora': [0,0,0,0,2,0,0,3,0],
    'yel': [0,0,0,0,0,0,0,0,0],
    'gre': [0,0,0,1,0,1,0,0,0],
    'blu': [0,0,0,0,0,0,0,0,0],
    'whi': [0,0,0,0,0,0,0,0,0],
}

```

As an example how can I reference array item [0] in sides['red'] ?

I have tried: 

```
sides['red'][0];
sides['red'[0]];

```

This is probably very wrong, can anyone suggest how I would declare it otherwise?
