Minimal NodeJS HTTP router, made for an example. Kudos to @asotirov
/* global module, console */
module.exports = function(http, port) {
'use strict';
var routes = {};
var exportMethods = {};
var middlewares = [];
['get', 'post', 'put', 'delete'].forEach(function(method) {
routes[method] = routes[method] || {};

Difference between composing funcions and returning result and composing functions and returning new function
; в този вариант, функцията compose връща директно резултата
; като изпълниш (f (g x)) - ако x е число, накрая просто ще ти върне някакъв резултат
(define (compose-first f g x)
(g (f x)))
; например това извикване ще ти даде директно резултат 2
(compose-first (lambda (x) (+ x 1)) (lambda (x) (- x 1)) 2)
; този compose, не ти връща директно скаларен резултат
