Keep your HTML CLEAN - Render at LIGHTNING SPEED

On April 7th, Google launched a new version of Gmail for mobile for iPhone and Android-powered devices. We shared the behind-the-scenes story through this blog and decided to share more of what we've learned in a brief series of follow-up blog posts. This week, I'll talk about how modularization can be used to greatly reduce the startup latency of a web app.

To a user, the startup latency of an HTML 5 based application is critical. It is their first impression of the application's performance. If it's really slow, they might not even bother to wait for the app to load before navigating away. Even if your application is blazing fast after it loads, the user may never get the chance to experience it.

Understanding scope in programming is key to appreciating how your variables interact with the rest of your code. In some languages, this can be quite straightforward, but JavaScript’s anonymous functions and event handling features, along with a couple of little quirks, mean that handling scope in your applications can become frustrating.

Are your web apps slow?Bug

Is there anything more annoying than a slow web application?

Great interfaces are nice. Pretty graphics are, too. Functionality is great. But if a web app doesn't perform fast enough, it'll end up going down the intertubes.

So, is your app slow? Do you know for sure? Do you know how to find out? And if you do find problems, do you know how to fix them, what to target first, and what not to do in your quest for better performance?

Even if you don't experience performance problems (yet),
you can almost surely speed things up.
