[removed] execute a bunch of asynchronous method with one callback

Question

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 : f

I've written some async utilities you might find useful, allowing you to write your example as:

function(callback) {
    async.series([
        asynch1(),
        asynch2(),
        ...
        asynchN()
    ], callback);
}

Or, if you wanted to run them in parallel, as:

function(callback) {
    async.parallel([
        asynch1(),
        asynch2(),
        ...
        asynchN()
    ], callback);
}

There are loads of other useful functions like async map/reduce too:
