I was searching for a best way to define a javascript class, and then, I found this:
http://www.phpied.com/3-ways-to-define-a-javascript-class/

So, it describes three ways:
1. using a function
2. using JSON
3. singleton (combination of 1. and 2.)

I couldn't find any article which describes what is the best way, in matter of compression, so I decided to test it by myself.
So I made three versions of my navigation system (I already had it in 2. way before I read that article), and I compressed them using google closure compiler, and these are result:

//usage: node --nouse-idle-notification --expose-gc --max-old-space-size=8192 memcached.js

var config ={
  port: 11211,
  max_memory: 300 // default 100M bytes
}

var net = require('net');
var LRU = function (max) { // this LRU implementaion is based on https://github.com/chriso/lru

I'm having trouble understanding the benefit of require.js. Can you help me out? I imagine other developers have a similar interest.

From Require.js - Why AMD:

The AMD format comes from wanting a module format that was better than today's "write a bunch of script tags with implicit dependencies that you have to manually order"

I don't quite understand why this methodology is so bad. The difficult part is that you have to manually order dependencies. But the benefit is that you don't have an additional layer of abstraction.

Eg. URL translating en page to es
http://translate.google.com/translate?hl=en&sl=en&tl=es&u=http://about.com

Define the web interface language to be English by adding
hl=en to the end of the URL and after the change the URL will look
like this:

   http://www.google.com/search?hl=en

When you use more than one setting code in the URL, you need to use

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
