Sessions at JSConf EU 2009 about JavaScript on Saturday 7th November

Remy Sharp (who is also doing the Full Frontal JavaScript conference (which we highly recommend)) will be talking about the HTML5 JavaScript APIs. HTML5 is all the rage with the cool kids, and although there's a lot of focus on the new language, there's lots of interesting new JavaScript APIs both in the HTML5 spec and separated out. This presentation will take you through demos and code behind the new JavaScript APIs, and explore where these features can be used.

No matter how awesome your JavaScript code is, we all face the same problem: how to squeeze it down the wire and get it loaded and running in the browser as quickly and efficiently as possible. There are about as many ways to approach this problem as there are developers trying to solve it, which makes the landscape of JavaScript Loading solutions confusing and painful to navigate. But it doesn't have to be so ugly. We're gonna break it down so you can come away feeling more confident in how best to load your JavaScript. Several common strategies will be covered, including:
•Build-time versus on-the-fly techniques
•Code organization/compression (minification, gzip, etc)
•File concatenation
•Inline scripts
•Dynamic parallel loading of JavaScript resources (LABjs, etc)
•Cache optimization (initialization profiling, on-demand loading, pre-fetching, etc)
