Free High Performance JavaScript
This book is a good reference on how to optimize JavaScript applications and also an interesting read in case you want to know how things work "under the hood".
Many of the techniques presented also works for other programming languages (and are well-known performance tricks) and can be used without increasing too much the code complexity, which is a huge gain, you're not just becoming a better JavaScript developer but also a better developer.
One thing that should be clear is that this book is NOT intended for BEGINNERS, since it already presumes that you have a good knowledge and experience with JS programming.
If you already read Professional JavaScript for Web Developers (Wrox Programmer to Programmer) (also written by Zakas), High Performance Web Sites: Essential Knowledge for Front-End Engineers and Even Faster Web Sites: Performance Best Practices for Web Developers you will find that some of the techniques were already present on those books, so if you're up-to-date with the new technologies/tools and been researching about the subject probably you already know a good part of what this book has to teach, nevertheless it still a nice and interesting read since it explains how the JavaScript engines work and why those techniques are faster, the fact that it is concise is a big plus too.
While reading Nicholas Zakas' "High Performance JavaScript", it occurred to me that there were actually two different reviews that I wanted to write. So, rather than try to reconcile them into one review, I'll simply apply them here as an ordered list.
(1) To continue with the JavaScript University metaphor (from my review of Zakas' Professional JavaScript for Web Developers (Wrox Programmer to Programmer)): Finals are coming up in Prof. Crockford's upper-division JavaScript class. You've been a diligent student all semester and although you're not failing, it always seems like you're somewhere in the middle of the pack. You want desperately to ace the final exam, so you reach out for some help. Zakas (the graduate student/teaching assistant for the class) offers to show you the thesis he is working on. Then It hits you like a bolt from the blue -- every bit of it resonates with you. "It's so simple! so clear!" you exclaim. The inner machinations of the language snap together in a way that makes it all feel new and exciting -- the possibilities are boundless! You go back over your notes. You were close -- oh so close -- the whole time. But the last little bits drop in. A refinement here, a re-factor there... and the next thing you know, things are blazing. Your pages load 60% faster, execution time is down an average of 40%. You're amazed at yourself. And when the grades for the final exam come back, you're pleased to see that you aced it (aside from that little Oops on scoping closures -- but you try to think of that as a conscious trade-off). Prof.
