Unique Code: Generate short IDs based on UTC Based on the C# version: http://schroedman.wordpress.com/2012/01/19/short-unique-id-in-c-without-using-guid/

uniqueCode.js

function uniqueCode(){
	var characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
	var ticks = (new Date()).getTime().toString();
	var code = "";
	for (var i = 0; i < characters.length; i += 2) {
		if ((i + 2) <= ticks.length) {
			var number = parseInt(ticks.substr(i, 2));
			if (number > characters.length - 1) {
				var one = number.toString().substr(0, 1);
				var two = number.toString().substr(1, 1);
				code += characters[parseInt(one)];
				code += characters[parseInt(two)];
			} else {
				code += characters[number];
			}
		}
	}
	return code;
}

cool to see this implemented in js! nice work!
