Facilitated by Neil Drumm, Drupal

Neil will share his learnings around best practices for implementing Javascript, focusing on making things fast. The session will draw on the work he has done on API.drupal.org, including smart dynamic “autocomplete” features. While Neil's focus will draw primarily on experiences with the JQuery library, he'll share thoughts on writing good and fast JavaScript for other frameworks as well. Some notes are at http://delocalizedham.com/node/21.
