Web 2.0 may be something of cliche but users are expecting to interact with web pages in an increasingly dynamic way. Javascript toolkits can make it easier to sprinkle a little AJAX magic over your web application and JQuery has garnered a lot of praise for being concise, intuitive and powerful in a Javascript idiom.
Remy Sharp will be talking about using JQuery in your application and there will be a Dojo exercise using JQuery.
Unfortunately Dan will not be able to make it as he has been called to work away from London on this date so the event will start a little later and instead the Dojo will be on general use of JQuery.
