Our book is ready for your download pleasure! And it’s packed full of info on all the tricks we use to make our apps and sites fast and snappy.
Co-written by Amy Hoy and me, it’s over 300 pages and is actually three books and our DOM Monster, a bookmarklet-based cross-browser performance evaluation tool.
Part 1: Dude, Where’s My Performance?
Get started with knowing what this is all about, why it is important and how to measure performance and master all the tools.
Part 2: Loadtime, or, The Land of Unicorn Tears
Loadtime is a sad time, a time of of enormous, slow-loading assets; of maxed-out request queues; of bloated, waddling DOMs. Of limp white screens. Most of the world’s worst web performance woes? They live and breed in Loadtime.
Part 3: Runtime, Cuz Tuning Loops Is Hardcore
See how to write slicker, sexier, faster JavaScript from the get-go. Micro-optimize without being premature. Learn the kinds of ridiculous optimization tactics that Gentoo tuner boys can only dream of. And yes, we’re teaching you how to unroll loops.
We’re totally framework-agnostic, so everything’s applicable to any and all JavaScript code out there! Whether you use Prototype, or jQuery or dojo, you’ll find that our tuning tricks can help speed things up!
And… introducing…. the… DOM Monster! See for yourself!
We’ve just released the beta of the JavaScript performance book we’ve been writing on for a while (we is my wife Amy Hoy and me!).
Without further ado:
More than a hundred pages on JavaScript loading performance and optimization techniques
The DOM Monster, a bookmarklet-based DOM analyzer, that tells you about performance problems of your page (from the perspective of the DOM, not the the network)
Free updates (it’s still beta, but pretty much complete anyway!)
I really hope you enjoy the ebook, and that it contains tons of stuff that you can use. Again, no matter what kind of JavaScript framework you use, the techniques described are universally usable.
The book will cover all sorts of topics around JavaScript performance, from perceptive loading performance all the way down to selecting between if and case statements.
It’s library/framework agnostic, so whether you use Prototype, jQuery, Mootools or any other libs, you’ll find that you’ll be able to provide faster-loading, better performing JavaScript to your users.
I’d like the web to be a better (and faster-loading!) place—and this ebook will help you get your sites literally up to speed with all the knowledge I’ve accumulated in years and years of web development and JavaScript programming.
So head over to http://javascriptrocks.com, sign up for the discount and you’ll soon will hold our beta release of the ebook in your (virtual) hands!
Andrew, being a UI developer by heart, doesn’t mess around and gives you hands-on examples for just about everything you can do with the “fraternal twins” Prototype and script.aculo.us.
You’ll learn how to really use all those fancy Prototype collection helpers (like each, detect, select, reject, partition, etc.), master the cool new custom events system, and seriously mess with the DOM; and how’ll see how Prototype can help you with everyday programming tasks with its extensions to functional programming and OOP. Plus of course how to make the most of Ajax and JSON. Last but not least, visual effects are explained, and also how they work by taking advantage of the DOM and how web browsers render websites.
The very interesting closing chapter shows you why things are as they are in Prototype, and will help you read the source code—and write JavaScript, Prototype-style.
The aerogel-weight mobile JavaScript framework, which also works great for Safari and Chrome extensions. The jQuery-compatible API makes it easy to pick up, and it's just 5k to 7k in size!
