Cool Techniques with AS3 Closures
// ------------------------------------------------------------------------------------------------
/**
* Why CLOSURES are great!
*
* Think of Closures as Functions within Functions... where nested functions have access to parent function variables
* and arguments. So, you may ask?
*
* Closures allow developers to temporarily cache data!
* Closures can simplify recursion or iterations (aka visitors pattern)
* Closures can solve real-world `callback` problems; especially powerful for asynchronous callbacks.

AS3 Closures Cleanup
public class Something
{
public function doSomething(index:int) : void
{
// Async closure for timer completion event
function onComplete_doSomething(evt:TimerEvent) : void
{
// Always clean up 1st, then notify listeners
timer.removeEventListener(TimerEvent.TIMER, onComplete_Timer );

Java function to split an array into chunks of equal size. The last chunk may be smaller than the rest.
// Example usage:
//
// int[] numbers = {1, 2, 3, 4, 5, 6, 7};
// int[][] chunks = chunkArray(numbers, 3);
//
// chunks now contains [
// [1, 2, 3],
// [4, 5, 6],
// [7]
// ]

Javascript micro-optimizations
NOTE: This document is OLD - and most of the tips here are probably outdated, since newer versions of Javascript have been
released over the years - with newer optimizations and more emphasis on optimizing newly supported syntax.
// Array literal (= []) is faster than Array constructor (new Array())
// http://jsperf.com/new-array-vs-literal/15
var array = [];
// Object literal (={}) is faster than Object constructor (new Object())
