Apr 07, Rob rated it it was amazing Shelves: While reading Nicholas Zakas’ High Performance JavaScriptit 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. Finals are coming up in Prof. Crockford’s upper-division JavaScript class. You’ve been a diligent student all semester an While reading Nicholas Zakas’ High Performance JavaScriptit occurred to me that there were actually two different reviews that I wanted to write. 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. Then It hits you like a bolt from the blue — every bit of it resonates with you. 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 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.

Crockford is pleased if a little disappointed that it took you this long to Get It and you’re the envy of your peers. At least until next semester’s RegEx class with Prof. Put scripts at the bottom of the document? So on the one hand you say: From this perspective, what is noteworthy about this book is that these best practices and techniques are all gathered up in one place and presented in a logical order; even if “you’re already doing it right”, it is still a worthwhile exercise to meditate on the specifics, and to really go deep on why these best practices are important.

Plus, it’s great to see the data — nothing beats a little chartporn for proving the point.

Review of “High Performance JavaScript” – Hacker Noon

Feb 28, Daniel R. I’ve routinely seen this book on short-lists of must read JavaScript books. I unfortunately waited too long to read it. As the foreword notes at the time the book was written the browser landscape was drastically different than it is as we start Certain chapters still hold bigh nuggets of advice but overall this book is hiigh longer a must read, in particular all of the browser benchmarks need to be rerun on modern browsers.

Loading and Execution is still important but doesn’t cover newer I’ve routinely seen this book on short-lists of must read JavaScript books. Perfkrmance and Execution is still important but doesn’t cover newer libraries. DOM Scripting advice still holds true and is a driver behind libraries like React.

Review of “High Performance JavaScript”

Most of Algorithms and Flow Control and Strings and Regular Expressions is still relevant, especially issues with backtracking. Responsive Interfaces and Programming Practices have some good ideas. The Ajax chapter is mixed and doesn’t include WebSockets as a transport mechanism. Tools has some good ideas but doesn’t cover newer browser debugging and profiling capabilities.

Jun 18, Dan added it Shelves: A disappointment, but mostly due performwnce its age.

When a book features performance testing of Google Chrome versions 1 and 2, you know something’s off. Finally forced myself to finish reading it, but found little of value in the back half of the book. The problem higy that almost everything in the book is a well-established best practice now, and if you’re even moderately up-to-date on writing good JavaScript, the book is almost all repetition.

That said, the big payoff was Chapter 3. Here is where the A disappointment, but mostly due to its age. Here is javazcript the DOM interaction comes into play, and the ideas of repainting and reflowing the page were examined.


There are also some interesting parts in Ch 5 regexes and 6 timers if you’re cc.zakas already familiar with the performance aspects of those features. I’d recommend intermediate and some advanced JS folks to skim certain chapters; just watch out for the speed tests — use jsperf.

Sep 22, Jamison Dance rated it it was ok. Full of outdated advice and old benchmarks. It wasn’t really what I was looking for. If you are nicgolas with IE 6, then there are some valuable tips, but if you are not and have some experience developing JavaScript, there is not much new here.

Nov 03, Daniel Lopez rated it it was amazing. Well written, easy to read and full of wonderful performance tips. Sep 13, Danial Kalbasi rated it it was ok Shelves: This book has few good points, but it almost irrelevant for the existing tech stack.

You might get more from google developer website rather than this jwvascript in terms of performance. Aug 08, Michael rated it really liked it. Excellent in depth look into some performance aspects of JavaScript code that might not be apparent even to weathered users of the language. Apr 28, Tony rated it really liked it Shelves: This book is not for a beginner in JavaScript.

It’s intended more as a “best practices” guide for people who are already at least intermediate in the JavaScript skills. If you have a hard time wrapping your head around object-oriented JavaScript and closures, you probably aren’t ready for this one, just yet.

The section on regular expressions and how they work, under the hood, was nearly worth the price of admission by itself. I’ve spent many years working with Perl, had the college-level course This book is not for a beginner in JavaScript. I’ve spent many years working with Perl, had the college-level course in deterministic finite automata, etc. I thought I knew that part frontwards and backwards.

I learned even more from hign book. What are the biggest barriers to fast page loading? How you determine which ones are holding up the show with your latest project?

It’s all in here. How slow is “slow? How do you do long-running tasks without running into that problem? Apr 26, Ulina rated it liked it Shelves: After three or four false starts, I was able to read this book until it was done.

I think it took me a while to get into this book because in the beginning it felt like he spent forever just talking about scopes. It could also have been that back then the Nook Color? Mostly meaning it didn’t save what page you were on last. Every time you open the pdf, it started back at the beginning. After a few pages, and I was able to get i I give it a 3. After a few pages, and I was able to get into a groove with the book.
