I had the privilege of presenting a couple months ago at the VNext Dallas user group on my experiences with Ext Js 4 during a recent engagement at a client. The slide deck is embedded below. If you’d like a little more context than what you can get in the slides (I make the slides like this for a reason, you know), I would point you towards the video of the presentation on UserGroup.tv, the guys that make the existence of the video possible.
I’d like to thank Shawn Weisfeld especially for recording this session, and for always showing up at the user group meetings no matter the size! His dedication to the community is unlike anything I’ve seen, folks.
