Emitting a timeout object in socket.io

JavaScript
1

I have this bit of code that’s causing an error and i have no idea why it’s causing a maximum call stack error…

const toggleReady = socket => async (acknowledge=()=>{})=>{
  acknowledge();
  const lobby = getPlayersLobby(socket.id);
  if(!lobby || lobby.players.length<2) return socket.emit('toggle-fail');
  const player = lobby.players.find(p=>p.socketId===socket.id);
  if(player){
    player.ready = !player.ready;
  }
  if(lobby.players.reduce((acc,r)=>acc&&r.ready,true)){
    startCountdown(lobby._id)
  }
  io.to('lobby-'+lobby._id).emit('upsert-lobby',lobby)
}

const startCountdown=lobbyId=>{
  const lobby = lobbies[lobbyId];
  lobby.startTimer = setTimeout(()=>{
    // initialiseGame(lobby);
    // delete lobbies[lobbyId];
    // closeLobby(lobbyId)
  },1000);
  console.log(lobby.startTimer)
  io.to('lobby-'+lobby._id).emit('starting-countdown');
}

I’ve found that if I change

  if(lobby.players.reduce((acc,r)=>acc&&r.ready,true)){
    startCountdown(lobby._id)
  }
  io.to('lobby-'+lobby._id).emit('upsert-lobby',lobby)

to:

  io.to('lobby-'+lobby._id).emit('upsert-lobby',lobby)
  if(lobby.players.reduce((acc,r)=>acc&&r.ready,true)){
    startCountdown(lobby._id)
  }

or if i change:

  lobby.startTimer = setTimeout(()=>{
    // initialiseGame(lobby);
    // delete lobbies[lobbyId];
    // closeLobby(lobbyId)
  },1000);

to:

  setTimeout(()=>{
    // initialiseGame(lobby);
    // delete lobbies[lobbyId];
    // closeLobby(lobbyId)
  },1000);

then i don’t get the error anymore, however that really makes no sense to me :stuck_out_tongue: any help would be greatly appreciated.

edit: So the problem has something to do with emitting a timeout using socket.io, i’d still like to know more about whats going on though
