Easy node.js programming (github.com)

Harvests: asynchronous programming as would be synchronous. Simpler alternative to promises and control flow libraries!

var harvest = require("harvests").create();

    harvest.let('father', loadPenguin, 'MrPenguin');
    harvest.let('mother', loadPenguin, 'MrsPenguin');
    harvest.let('family', loadPenguinFamily, wait('father'), wait('mother'));

    harvest.do(function(family){
        console.log(family); //also in  harvest.father, harvest.mother, harvest.family you got values
    }, wait('family') );

    harvest.onFail(function(error, variable, index){
        console.log("Well, move those penguins to the South Pole...", error, variable, index);
    });

Promoses and flow libraries have steep learning curve
