I need to execute a bunch of asynchronous methods (client SQLite database), and call only one final callback.

Of course, the ugly way is:

execAll : function(callBack) {
        asynch1(function() {
            asynch2(function() {
                ...
                asynchN(function() {
                    callBack();
                })
            })
        });
    }

But I know there are better ways to do it. Intuitively I would detect when all call back has been called with a counter to call the final callback.

I think this is a common design-pattern, so if someone could point me in the right direction...

Thanks in advance !
