Socket.io typeof error, any help please?

Here's the relevant part of my codesocket.on('disconnect', function(){ console.log(rooms.length) var destroyThis = null if (typeof socket.store.data.roomi == 'undefined') { for (var i in rooms) { if (rooms[i].roomSocket.id == socket.id) { destroyThis = rooms[i] } } if (destroyThis !== null){ rooms.splice(destroyThis, 1) } console.log(rooms.length) } else { var roomID = socket.store.data.roomi for (var i in rooms[roomID].clientSockets) { destroyThis = i } } if (destroyThis !== null) { rooms[roomID].clientSockets.splice(destroyThis, 1) } rooms[roomID].roomSocket.emit('remove user', socket.id) }) and I get the error if (typeof socket.store.data.roomi == 'undefined') { ^ TypeError: Cannot read property 'data' of undefined To me this makes no sense, I'm trying to check if it's undefined and it's throwing an error because it's undefined?
