Javascript coding test

Please implement the following. There is no time limit or other restrictions apart from the mentioned.

  1. Without using Javascript's bind function, implement the magic function so that:
var add = function(a, b) { return a + b; }
var addTo = add.magic(2);

var say = function(something) { return something; }
var welcome = say.magic('Hi, how are you?');

addTo(5) == 7;
welcome() == 'Hi, how are you?';
  1. Say you have a http://basketball.example.com/thisweek.json HTTP endpoint that returns the following JSON:
{
  "week": "51st of 2011",
  "games": [
    { "url": "http://basketball.example.com/game/1" },
    { "url": "http://basketball.example.com/game/2" },
    { "url": "http://basketball.example.com/game/3" },
    { "url": "http://basketball.example.com/game/4" }
  ]
}

The games entry is dynamic and may include arbitrary URL’s. Each of the URL endpoints returns some game data:

{
  "id": "1",
  "teams": [
    {
      "name": "Lakers",
      "score": 79
    },
    {
      "name": "Bulls",
      "score": 99
    }
  ]
}

Given that jQuery is available and loaded, write a summary function that prints a list of all scores formatted like Lakers 79 - 99 Bulls.

  1. Write a function that creates a deep copy of an object, without using JSON.stringify.

  2. Given the following tab-panel.html:

<html>
  <head>
    <link href="tab-panel.css" rel='stylesheet' type='text/css'></link>
  </head>
  <body>
  	<section>
  		<h2>Tab Panel One</h2>
  		<article title="Tab One">
  			<h3>Tab One</h3>
  			<p>Panel One - tab One</p>
  		</article>

  		<article title="Tab Two">
  			<h3>Tab Two</h3>
  			<p>Panel One - tab Two</p>
  		</article>
  	</section>
  	<section>
  		<h2>Tab Panel Two</h2>
  		<article title="Tab One">
  			<h3>Tab One</h3>
  			<p>Panel Two - Tab One</p>
  		</article>

  		<article title="Tab Two">
  			<h3>Tab Two</h3>
  			<p>Panel Two - tab Two</p>
  		</article>
  	</section>
  	<script src="tab-panel.js" type='text/javascript'></script>
  </body>
</html>

And the following tab-panel.js part:

var tabDemo = function() {
	for(var i = 0; i < document.body.children.length; i++) {
		child = document.body.children[i];
		if(child.tagName.toLowerCase() != 'section') continue;

		t = new TabPanel();
		t.init(child);
		window.panels.push(t);
	}
};
var panels = [];
window.onload = tabDemo;

Without using jQuery, implement the TabPanel component that handles tabs switching. Add any applicable stylings to tab-panel.css (we aren't assessing artistry abilities - we are just after clean functional css).
