deepEquals in CoffeeScript

	deepEquals = (objA, objB) ->
	# Simplest of all checks
	return true if (objA is objB)

	# Both parameters need to be objects
	return false if (typeof objA isnt 'object') or (typeof objB isnt 'object')

	# Special case for Date objects
	if (objA instanceof Date) or (objB instanceof Date)
	return false if ((objA instanceof Date) isnt (objB instanceof Date)) or (objA.getTime isnt objB.getTime)

Chainable type checks in CoffeeScript (Method chaining with type checks) Also allows to wrap type checks into an object, which is a safer option than a switch-case-typeof check AMD definition included :)

	do (root = exports ? this) ->
	'use strict'

	root.check = (variable, checkObject) ->

	stringedVar = {}.toString.call variable
	typeName = stringedVar.slice(8, stringedVar.length - 1).toLowerCase()

	checkType = (typeString, cb, inverse) ->
	if inverse

First draft of the MilkSugar web framework based on jQuery and Handlebars. This is not fully functional neither complete.

	((window, MilkSugar, $) ->
	"use strict"

	# Rebind method for JSHint
	check = window.check

	class MilkSugar.App

	constructor: (assets = ['image', 'view']) ->
	if assets?

Simple namespacing mechanism in CoffeeScript

	namespace = (name, func) ->
	if name.indexOf('.') > 0
	nameArray = name.split('.')
	else
	nameArray = [name]

	context = window
	for i in nameArray
	context = context[i] or= {}

Rudimentary Entity-Component-model in CoffeeScript

	class Entity
	componentList = {}

	constructor: (@name = @constructor.name) ->

	get: (componentName) ->
	if componentName
	componentList[componentName]
	else
	Object.keys componentList

Alternative approach to converting CSON (CoffeeScript Object Notation) to JSON (JavaScript Object Notation) which does not require outer curly brackets to be present in the CSON.

	fs = require 'fs'
	path = require 'path'
	coffeeScript = require 'coffee-script'

	convertCSON = (csonObject) ->
	return unless csonObject?

	completeObject =
	"csonObject = {
	#{csonObject}

Simple StringReader class in CoffeeScript which can be used to extract specific tokens from a bigger string. Inspired by http://brandoncodes.wordpress.com/2012/04/07/add-some-syntactical-sugar-to-your-coffeescript/

	class StringReader
	buffer = ""

	constructor: (@input) ->
	@reset()

	readUntil: (character, omitCharacter = false) ->
	loop
	break if @currentIndex is @input.length

A bit more advanced Entity-Component-Model (based on https://gist.github.com/4402499) which takes advantage of the dynamicness of JavaScript by adding the prototype and property functions from components to the entity itself.

	# Example 1
	# Adding properteies to Component instances
	console.log '--- Example 1 ---'
	comp1 = new Component('comp1')
	comp1.test = -> console.log 'Comp1'

	comp2 = new Component('comp2')
	comp2.test = -> console.log 'Comp2'

	myEntity = new Entity('myEntity')

	buffer = ""

	constructor: (@input) ->
	@reset()

	readUntil: (character, omitCharacter = false, notFoundFn) ->
	loop
	if @end()
	notFoundFn(buffer) if notFoundFn
