JavaScript Performance


We're going to talk about JavaScript performance in regular web pages, AJAX applications as well as widgets.

Sergey Chernyshev, will talk about JavaScript on the wire, how it affects web site performance and different techniques you can use to improve your JavaScript-heavy applications as well as just regular sites that might be hurt by badly implemented JavaScript. Sergey will also cover some network behavior specific to external JavaScript applications and why you should be careful with all the Widgets you want to plug onto your page.

Ning Zhou (, organizer of the NY JavaScript Meetup (, will discuss JavaScript performance in the browser. He will start with the importance of JavaScript performance in today's RIAs followed by a look at how JavaScript performance differs in various browsers and how this affects the coding approach. Then move on to common techniques that can help speed up client-side code. And lastly, Ning will discuss bottleneck detection in your JavaScript code so you can invent your own optimization techniques and provide a better overall user experience.
