Faster Filtered Arrays in Javascript

The secret to snappy user-interfaces built with web technologies is efficient DOM manipulation. Unfortunately, commonly used data transformations like .map(), .filter() and, .sort() - while blazingly fast - are wildly inefficient when applied to constantly changing data sets. If left unchecked your DOM manipulations could inherit those inefficiencies where they are made painfully obvious to the end-user.

In this talk we'll examine this problem, a popular workaround, and the far superior solution being developed by the CanJS (http://canjs.com/) team at Bitovi (http://bitovi.com/).
