JavaScript Performance Optimization
Ezra Parker
Online ColdFusion Meetup
December 8, 2011

Building complex JavaScript applications has never been easier, as libraries such as jQuery enable developers to write expressive, simple code that is reliably compatible with a wide variety of browsers. While these frameworks offer many advantages, they also make it relatively easy to write JavaScript code that may not be optimally performant.

This session will cover a number of areas of concern when attempting to optimize for performance, demonstrating methodologies, tips and tricks that can be used to avoid some of the more common pitfalls. We will also talk about script loading, and discuss various approaches for loading JavaScript files that can be used to improve the user experience.

This presentation was originally given at cf.Objective() 2010:

Ever since the introduction of jQuery and other JavaScript/Ajax libraries, you don't need to know Flex in order to construct complex, fully-featured and user-friendly Rich Internet Applications. If you're already familiar with jQuery and want to take your RIA development to the next level, this session will demonstrate the use of the jQuery user interface library widgets and the jqGrid plugin to create an advanced single-page application with a consistent look and feel that can be easily re-skinned using an existing jQuery UI theme or by using ThemeRoller to craft a custom design.
