why isn't the socket connection counter updating?

this is the code I have in an index.html (client). Im wondering why the number is not being incremented. I expect on each time a socket connect I give it a unique name.

 var number = 0;

    socket.on("connect",function(){
         number = number+1;

        socket.emit("add user","user"+ number )


    })

but when i have this server

io.on("connection", function(socket){

    console.log("io.onconnection")
    socket.on("add user", function(data){ 
    console.log(data)
    })
});

on each connection i get logged user1, why isn't the second connection user2? thanks

Because javascript is a client side, and number will always be 0 every time the page refresh/load.

You can count the number client connected in your websocket, server then pass it to js and then you can increment.
