Superhero.js. Using Google's Closure to Compile and Verify your JavaScript. 7, Mar 2013 A large application is nearly guaranteed to come with an equally large amount of JavaScript attached to it.
During development it makes sense to divide the JavaScript of the application into multiple sensibly named files both to make finding specific functionality in the code base easier, and to keep the file length to a reasonable size for readability/comprehension purposes. More importantly though, this allows you to build modular, reusable components by separating functionality and sharing common methods within the application.
However, when it comes time to move your site to the production environment, this development processes' inefficiencies become noticeable in slow loading pages. The most obvious pitfall is the fact that having multiple different files means that new HTTP requests have to be issued for each file, bringing with it an additional round trip time. Introducing Google Closure. Using Web Workers to Speed-Up Your JavaScript Applications. The performance of JavaScript applications running in the browser has increased considerably over the past few years.
This is mainly due to continued work on the underlying JavaScript engines (such as V8) that actually execute the code. But as these JavaScript engines get faster, our web applications also demand more. The introduction of JavaScript APIs like the File API has made it possible to write JavaScript applications that are undertaking some serious computational tasks on the client-side. Despite the improvements in JavaScript engines, it is not uncommon for users to encounter frozen user interfaces as the browser works through resource intensive tasks. A Deeper Dive into jQuery Mobile. There’s no doubt that mobile Web applications are here to stay.
As I said at the start of the previous article in this series, talk to any C-level executive at a major company or any technology startup, and they’ll tell you about mobile apps. jQuery Mobile (jQM) provides a JavaScript framework that allows developers to easily add a mobile look and feel to their Web applications. In this article I’ll dig into some advanced features of jQuery Mobile that—with some programming—a developer can use to provide an application that looks and feels very similar to a native app running on a device. Here’s what I’ll cover: $.mobile. Configuration of jQuery Mobile jQM comes with a new object—the mobile object—which is available off the main jQuery object, $.
Note: The $.mobile object is not available until after the mobileinit event is fired. In the previous article, I described examples of using a “data-”attribute on elements. For example, the $.mobile object can be extended as follows: Announcing the jQuery Plugin Registry.
