Ideally, the browser stores the JavaScript in a pre-parsed or pre-complied format in the cache or provides a mechanism to share the JavaScript between pages so that on a page transition the application doesn't experience the performance hit of reloading and reparsing the Java Script library. A technique used today is to share the JavaScript in a hidden iframe between pages, it would make sense that this support is native in the browser.
