JavaScript Performance
This location is shown only to members
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.
Getting there
Interactive One's offices are near Canal street 1 and A/C/E stations:

Yes, this is the same event ;) Ning just posted it on JS Meetup instead of linking to Web Performance. It doesn't matter which one you RSVP to, you'll get on the list.

Too bad you can't attend - nothing beats live discussion. We'll definitely have slides available.
I'm not sure if we'll have more then that - I'm trying to do recording, but can't promise anything yet. I'll definitely update the list if it turns out good.

Andrei KashcheyeuI want to say thank you Sergey and Ning for interesting topic. Actually I was #200 member of this meetup group and Segey presented to me two interesting books: High Pefomance Web Sites and Even Faster Web Sites by Steve Souders. I started to read High Perfomance Web Sites. If you are interested to improve your knowledge in Javascript and web development, I recommend reading these books and visiting next meetup!

Thomas HallockSome nice tips on how to improve Javascript performance. Also, it was useful to learn that there is an important difference between performance, scalability, and reliability.

Adam SmithOverall, generally good. I found Sergey to be a bit more engaging than Ning, although the acoustics and presentation set up in the area of Interactive One do leave a little to be desired. I'll attribute it to the volume of the voice. I definitely learned a thing or two, so I appreciate it being organized. Knowledge sharing is fantastic and it's also nice to meet other like-minded folks face-to-face in the real world.

Humm . . . a little confused . . .
Sergey, is this NY Web Performance meetup (this time) being combined with the meetup of the NY JavaScript group? Sounds like it . . . both at the same location . . . and you are talking at the JavaScript, and Ning will talk at this meetup . . .
