+1 to that, benji, and with another:

<tip type = "Programming" author="Ben G.">
Use objects or classes (depending on your language's support) whenever you
can. They provide the clean-code benefits of "functionizing", with the added
benefits of increased readability. In JavaScript, for example, you can use
custom objects to package the attributes and methods that refer to an
object, thus making references to that object logical, compact and easy to
read.

Example:

<SCRIPT LANGUAGE="JavaScript1.2"><!--
	var ben = new person("Ben Gustafson", "Webmaster", false);
	if (!ben.hasCoffee)
		ben.getCoffee();
	alert(ben.name + " has coffee? " + ben.hasCoffee + "!");

	function person(name, occupation, hasCoffee)
	{
		this.name = name;	// attribute of person object
		this.occupation = occupation;
		this.hasCoffee = hasCoffee;
		this.getCoffee = getCoffee; // method of person object
	}

	function getCoffee()
	{
		this.hasCoffee = true;
	}
//--></SCRIPT>

</tip>
