Naming the callback is not working

[daroay]

if I do:

jugChat.subscribe('myChannel', function(data){
  alert('success');
});

It works, but if I do:

jugChat.subscribe('myChannel', subscription);

var subscription=function(data){
  alert('success');
}

It is not working.

That is because you're not writing valid JavaScript. The subscription variable needs to be assigned before you use it, or you need to use a named function.
