Scripts are the most painful resource to load in your page - they slow down the page more than images, stylesheets, even Flash. Why? Because when browsers start downloading a script, they stop rendering the page and downloading other resources. Even newer browsers that tout parallel script loading (IE8, Firefox 3.5, Chrome 2, Safari 4) still block rendering and downloads when loading scripts. In this talk, I'll present several techniques for avoiding these problems including splitting the initial payload, loading scripts without blocking, and coupling asynchronous scripts. This talk is only relevant for web sites that use JavaScript and want to be fast and have happy users.
