javascript - How to remove websocket connection onClose properly -

please take src-code:

var clients         = {}; // map<string, connection> clients var clientsreverse  = {}; // map<connection, string> clientsreverse  websocketserver.on('connection', function(newclient) { // newclient connection object      newclient.on('message', function(message) {          var data = json.parse(message);          if (clients[data.name] === undefined) {             clients[data.name]        = newclient;             clientsreverse[newclient] = data.name;         }          // ...      });      newclient.on('close', function(){         log(clientsreverse[newclient]); // prints same string          // remove closed connection         var key = clientsreverse[newclient];         delete clientsreverse[newclient];         delete clients[key];     }); }); 

i have remove connection if client gone away. can see i'm using 2 arrays this, unfortunately not work. if try disconnect 3 random clients, log print same name...

any idea i'm doing wrong?

neither clients nor clientsreverse array. objects. objects act kinda hashmaps in javascript, can access properties strings. example:

var = { b: 5 }; console.log(a['b']); //5 

if try make index out of object (newclient object), tostring first. result of newclient.tostring() [object object], , every object use, doesn't matter it's different object. that's why though use different newclient objects, resolves same key.

i'm not sure want achieve here. can try using arrays ([]), can have numerical indexes. can try using kind of unique property of client, id or name perhaps?
