Three.js, first animation

So, i tried my hand on three.js to have a small animation... basically a CUBE having shadow, and camera is moving in a circular fashion around the cube.
Very basic but first one.

important points,
1) lights are very important, without that it will be black.
2) high light number produce more bright light

Code is here,

window.onload and addEventListener usage

main.html:
<script src="main.js"></script>
<input type="button" id="test" value="click here"></input>
<div id="display"></div>

main.js:
var button = {
counter : 0,
click : function() {
button.counter++;
document.getElementById("display").innerHTML = button.counter;
}
};

window.onload = function()
{
var b = document.getElementById("test");
b.addEventListener("click", button.click, false);
}


Important notes:

Without this onload function, putting 'addEventListener()' directly in global scope will give error, because we are attaching <script src="main.js"> before the <input type> for 'test'. So, JS will not get this element in DOM tree. hence, onload function will wait till document is not getting loaded fully and all elements are available in DOM tree.

Handmade UnitTest framework for JavaScript

Well, I was also needing a UT framework (a very simple one) and decide to write my own in JS.

At the same time, i realize that i need to have a public GIT repository to keep all my sample code, hence i have created this link,
https://github.com/tapeshmaheshwari/JavaScript.git


So, i wrote my first JS program which is a Unit Test Framework.
@ https://github.com/tapeshmaheshwari/JavaScript/tree/master/unittest


It looks like below and based on 'assert' function.

JavaScript ... first post

I have decided to learn JavaScript a bit seriously. Why? because I think there is a lot of potential in this language. From mobile apps to gaming and animation to pretty dynamic UI, all can be done with JS.

In short, JavaScript future is bright and if someone interested in web programming, it's the must language.

Here are some good resources i found for Web programming:

cofee console - fast way to write js code
sublime editor - nice editor to write JS code

Some code example,
http://github.com/tkmagesh => "repositories" => Cisco-AdvJs-Aug-2014

Some JS libraries:
http://underscorejs.org/
http://backbonejs.org/
https://angularjs.org/

Unit test and tools:
unit test: grant.js (complete echosstem for application workflow)
bower - dependency managment
unit test - jasmin , mokka , signon

Extra:

How to run a simple HTTP server using python

python -m SimpleHTTPServer

Just run this and root directly from wherever you are running this will become the core root directly and search for index.htm (or otherwise just do the file listing)
