Broadcasting to a array variable in node

Question

Broadcasting to a array variable in node

for (var key in rows) {

    var userid = rows[key].user_id;

    listsusers.push(userid);
}

console.log(listsusers);

shows output [ 1, 2, 3, 4 ] in terminal

I need to broadcast it to corresponding users 1,2,3,4 with their user id's.

I tried this to broadcast:

socket.broadcast.to(listsusers).emit('user_count', {
    'user_id': userid
});

node.js
socket.io

Answer 1

I solved it by putting the broadcast statement inside the loop

   for (var key in rows) {

    var userid = rows[key].user_id;

    socket.broadcast.to(userid).emit('user_count', {'user_id': userid}

    });

    console.log(listsusers);
