PDF Ebook You Don't Know JS: Async & Performance, by Kyle Simpson

No matter how much experience you have with JavaScript, odds are you don’t fully understand the language. As part of the "You Don’t Know JS" series, this concise yet in-depth guide focuses on new asynchronous features and performance techniques—including Promises, generators, and Web Workers—that let you create sophisticated single-page web applications and escape callback hell in the process.

Like other books in this series, You Don’t Know JS: Async & Performance dives into trickier parts of the language that many JavaScript programmers simply avoid. Armed with this knowledge, you can become a true JavaScript master.

With this book you will:

• Explore old and new JavaScript methods for handling asynchronous programming
• Understand how callbacks let third parties control your program’s execution
• Address the "inversion of control" issue with JavaScript Promises
• Use generators to express async flow in a sequential, synchronous-looking fashion
• Tackle program-level performance with Web Workers, SIMD, and asm.js
• Learn valuable resources and techniques for benchmarking and tuning your expressions and statements

7 of 7 people found the following review helpful. Tremendous, but challenging. By Adam Rackis This penultimate edition of the You Don't Know JS series explores everything async: Promises and Generators, mainly. As usual, the content was deep and the examples challenging (in this edition especially so). This book is certainly not for the feint of heart; if you're not an advanced developer and you don't know about these topics, you might consider reading some simpler introductory material online before tackling this.The one negative was the editing; there were many places where a sharp editor could have really clarified and simplified matters. There were a number of places where I'd read a section two or three times, and basically say to myself, "so Kyle's saying X Y Z," and then three paragraphs later see him say almost verbatim, "X Y Z." On the one hand it's always nice seeing that you correctly interpreted something difficult, but on the other a more straightforward presentation would have helped. And many other areas would have similarly benefited from a tightening up of the language, and stating more clearly and up front what the lessons to follow were.But to be clear, the above criticism should not for a moment prevent a senior JS developer from tackling this book. It'll be well worth your time, and you'll no doubt learn a tremendous amount.

8 of 9 people found the following review helpful. Promises make JavaScript almost a new programming language By Jim Fathman Kyle Simpson continues to impress with his in-depth study of JavaScript in this essential book series. This may be his best book yet for those who aspire to JavaScript mastery. Promises make JavaScript almost a new programming language, and if you read the book carefully and try the examples, you will come to appreciate why Promises are so important.The book tends to concentrate more on the why than the how, so before beginning, I suggest you spend some time experimenting with JavaScript asynchronous programming using the Node.js Async and Bluebird libraries. Once you are familiar with the raw mechanics of async programming, the book’s thorough treatment and rationale for the why of Promises will be easier to comprehend.JavaScript is arguably the most important programming language in the world, but it is not standing still, basking in its glory. JavaScript is continually reinventing itself, modernizing, and as developers we must trust in the wisdom behind the changes and embrace new language features. To do so properly requires guidance from experts, and there is currently no finer resource than this book series.

4 of 4 people found the following review helpful. Promises and Generators By Tomislav Pesut Excellent review of async programming in Javascript with a lot of focus on Promises and Generators. Both are important concepts that are only going to get more relevant.
