JavaScript itself gives developers enough power to beautify messy async code, already. Below is the rewrite of the first example in that page, with async function composition:

====

/* https://gist.github.com/1250314 */

var db = require('somedatabaseprovider'),

      compose = require('functools').compose;

compose.async(getApp, connect, select)({ url:'/price', host:'host', pass:'123' }, function(error, shift){

  shift.conn.close();

  shift.res.send(shift.products[0]);

});

====

It's that easy to abstract those messy callbacks using some functional tools.
