Send message to other rooms in Socket.io

I Know how to send message to all the clients in the same room. I am using below code to send message to clients in the same room (server side).

io.to(Array.from(socket.rooms)[1]).emit("send message","We are in Same room")
//Array.from(socket.rooms)[1] -> getting room number from the map

But now I want to send message to All the clients who are not in current room.

Get the array with socket IDs from specific room and using that array to exclude from all connected sockets:

const socketsFromRoom = Array.from(await io.in("my_room").allSockets());

Array.from(await io.allSockets())
  .filter((socketId) => !socketsFromRoom.includes(socketId))
  .forEach((socketId) => {
    io.sockets.sockets.get(socketId).emit("send_message");
  });
