Array.prototype.last = function() {
	return this[this.length-1];
}

Usage:
var colors = ['red', 'blue', 'green', 'black'];
colors.last() // -> 'black'

Trim string

String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, '');
}

Usage:
var sentence = "    We all like candy, don't we?     ";
sentence.trim() // -> "We all like candy, don't we?"

Truncate string

String.prototype.truncate = function(len, preserveWords, app) {	
	var str = this;
	var defaultApp = '…';
	app = typeof app == 'undefined' ? defaultApp : app;
	
	if( str.length < len ) 
		return str;
	
	if( ! preserveWords )
		return str.substr(0, ( app == defaultApp) ? len - 1 : len - app.length ) + app
	
	str = str.replace(/\s+/i, ' ').replace(/\r\n/i, ' ').replace(/\r/i, ' ').replace(/\n/i, ' ');
	
	if( str.length < len ) 
		return str;

	var truncatedString = '';
	var words = str.trim().split(' ');

	for(var i=0; i= len)
		{
			truncatedString = truncatedString.trim();
			return ( truncatedString.length == str.length ) ? truncatedString :  truncatedString + app;
		}		
	}
};

Usage:
var text = "This is a test for my truncation method.";
text.truncate(10); // -> "This is a t…"
text.truncate(10, true, " [more]"); // -> "This is a [more]"
text.truncate(7, true); // -> "This is…"

How to deal with Internet Explorer 6?

• Try to “fix” your page for IE 6: Assuming a certain level of skill (and luck), one is usually able to trick IE into rendering one’s website somewhat acceptably, but advancing technology makes it more and more laborious and time consuming to do so. Some developers are estimating more than 30% of their time to be going into solving browser specific problems. This solution is still chosen by most agencies and often leads to unpaid or not previously estimated working time which usually makes nobody happy. Weapons of choice are conditional comments or CSS “hacks”, lots and lots of Javascript (often causing additional accessibility issues) and dirty tricks à la CSS expressions and layout tables.
• Ignore IE 6: This option is chosen by a few smaller and mostly private sites but generally regarded as discriminating. If you decide to simply “not do anything” to deal with our favorite browser, you’ll in the best case show a clear disrespect for your visitors who are using IE 6 to browse your pages.
• Ignore IE 6 and tell your users that they’re idiots and should GTFO: Well, unless you’re trying to p*ss people off or keep your site a private venture, this option is really not very recommendable. Still—it’s all out there.
• Ignore IE 6 but tell your users that you do so and offer help: Recently more and more (bigger) sites such as Youtube and Digg have announced, that they are going to drop IE 6 support. The common practice in these cases seems to be to display a small notification telling the user about the decision and offer download links for the latest browsers from different vendors. While this seems like a good idea in the first place, it might backfire and leave most IE 6 users helpless, though: Big companies rely on browser based intranet applications, which simply rely on IE 6. And since it’s not possible to install multiple versions of IE (or almost not possible) on the same computer, IE 6 remains the browser “of choice” in many cubicles out there, since IT departments and security guidelines rarely allow it for the regular employee to install his own additional browser, such as Firefox or Chrome. While upgrading or switching the browser is good advice, it’s in this case merely a slap in the face since the user simply can’t follow this advice.

What’s left?

• my page has been constructed using valid and semantically meaningful mark–up
• and that the content within my page is more important than the presentation

• I want to push agencies to stop supporting IE 6
• I want companies as private users to update their browsers or (even better) switch to a standard compliant browsers
• I want my users to stay and enjoy the content provided on my page and hopefully come back
