Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

View modules.js
/**
* Globals
*/
var Carrousel = function(elem) { this.init() };
Carrousel.prototype = { init: function() {} };
new Carrousel();
/**
* Namespacing
* - No globals (only the namespace variable itself is global)

Primitive Types & Reference Types in JavaScript

An explanation of JavaScript's pass-by-value, which is unlike pass-by-reference from other languages.

Facts

  • JavaScript has 2 kinds of variable types: primitive and reference.
  • A fixed amount of memory is reserved after creation of every variable.
  • When a variable is copied, it's in-memory value is copied.
  • Passing a variable to a function via a call also creates a copy of that variable.
