Trading description for time is the essence of computation
One way of characterizing computation is that we want to go from an abstract mathematical "timeless" description of an object to a concrete representation which can be manipulated symbolically.
Computation can be defined as the process which goes from the abstract to the concrete, and the time which this process takes is one of the central considerations of CS as a field.

My last advice is that sometimes it is important not to overthink epigrams or koans, but let understanding come naturally with experience.

 Q:

Skip to main callback with result in async waterfall node js

Am new to node js and am working with async waterfall.
var methods = function (req, res) {
async.waterfall([
    func1(req, res),
    func2,
    func3
], mainCallback);
};

app.get("/create", function(request, response)
{
  methods(request, response);    
});

function func1 (something, res, callback) {
    if(something == 0)
    {
     callback (null, res, somethingelse);
    }
    else
    {
     mainCallback("success");
