Javascript multidimension arrays

I am creating a chat application and I ran into scaling issues. I want to create an array "roomspace" which holds multiple "room" and each room holds multiple "users". I can obviously hard code this thing but for the scale of scaling I need to declare something like roomspace[][]. But I am not being able to declare in this way and also i have been running problems while traversing the array. Can someone please give me a sample of how can this be accomplished. I would really appreciate that.

Here is a small model for you. I made the roomSpace an object in which you can access the room by name than index.

Also you have the constructor for room object which knows how to handle a room

And the last loop demonstrates how you can traverse through the entire roomSpace.

You can add any number of rooms and any number of users to it dynamically. You can scale this model up by adding more methods and properties.

//Your room space
var roomSpace = {};    


//This function returns a room object
function constructRoom() {
    return {                
                users: [],        
                addUser: function(userName) {
                    this.users.push(userName);
                },

                clearUsers: function() {
                    this.users = {};
                }    
            }
}     



//Here you add rooms    
roomSpace['javascript'] = constructRoom();
roomSpace['php'] = constructRoom();

//Add some users
roomSpace['javascript'].addUser('charlie');
roomSpace['php'].addUser('john');


//Clear the whole room space of users
for (var room in roomSpace) {
  roomSpace[room].clearUsers();
}
