I mean in general with JavaScrips trying to save dataload by sending diffs of that JavaScripts instead of full new version -- does not worth the complexity of dealing with it. Diff functionality is more complex and therefore: - Requires a lot of time to develop and maintain. - Could have bugs which might result in a weird web application behavior. Bandwidth is not as expensive as the overhead of maintaining JavaScript Diffs.
