ES6-like string functions (they are not really compatible - like not at all - to the official specification though)

	do (String) ->
	String::contains or= (searchString, position = 0) -> @toString().indexOf(searchString) >= position
	String::startsWith or= (searchString, position = 0) -> @toString.toString().indexOf(searchString) >= position
	String::endsWith or= (searchString, position = @length) -> @toString().lastIndexOf(searchString) is position - searchString.length
	String::repeat or= (count) ->
	newString = ''
	newString += @toString() for [1..count]
	newString
	String::toArray or= -> @toString().split ''
	String::reverse or= -> @toArray().reverse().join ''

Helper function, which either creates an object with empty functions from an object with primitive types or an array - or - converts an object with functions into an object with function and method chaining

	chainedOp = (obj) ->
	result = {}
	resultFunc = (i) ->

	if Array.isArray obj
	(result[i] = -> @) for i in obj
	else
	for key, value of obj
	if typeof value is 'function'
	result[key] = (args... ) ->

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')

	class StringReader
	buffer = ""

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

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

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}

	else
