You Don't Know JS: Types & Grammar

I'm not a noob for JavaScript, but I'm not an expert either. Up until now, I've been using a minimal of JS to develop small single page apps to manage my Java web apps. Things have changed and now, I'm expected to become a "Full Stack Developer" concentrating on the Front end of my Apps.This is where this book (and ALL the others in this series) excel. Those of us that learned "just enough JavaScript" to get by can eat this stuff up.In this book and the entire series, Kyle presents the good, bad and fugly of JavaScript. He tells you how to implement best practices and how to get around and even embrace some of the ugly parts of JavaScript. He tells you WHY some of the "features (not bugs)" were implemented and HOW the JS "compiler" implements the features of JS. This is EXTREMELY helpful in understanding the language (I wish there were Java books like this.)These are not beginner books, but I would say that EVERY JavaScript Developer should read and have on their Kindle or Bookshelf. It should be REQUIRED reading for those who want to become JS experts. And I LOVE Kyle's style of writing. It hooks you and keeps you interested.Thank you Kyle Simpson for such great books.

This is on of a series of books on JavaScript. Do yourself a favor and buy he series. It's absolutely the best information I have read on the js language. This is the third book in the series. The first book seems to be for complete newbies, but the rest of the series covers language concepts, how the engine processes the code, and it leads you to the promise land of understanding how to use the language optimally, and shines a light on how many have gone to great length to use the language like in a object oriented fashion, and failed.I walk away with a clear understanding of how I want to use javascript from now on.

Nick Zakas's "High Performance JavaScript" has always been my favorite JS book for senior devs. I can honestly say this piece surpasses that. It's probably the most dense 177 pages I've ever seen. The table of contents accessible from Amazon will enumerate the topics discussed; for the purpose of this review let it suffice that each area is ripped apart to reveal details that virtually any senior developer will be unaware of, and likely be surprised by. The section on loose equality alone is something I anticipate referencing in the future. Very well done.

Awesome book!Content is clear, easy to understand, but deep enough to really cover all the fundamentals. Recommended for anyone, who is familiar with JavaScript and wants to get a deeper understanding of what is going on beneath the hood.This is especially important for front-enders, who never really touch many important aspects of JavaScript and writing efficient, well-thought code is a major problem for them.

This series from Kyle Simpson is hands down the best explanation of JavaScript I have read. This series of books has helped me accept how "this" works in JavaScript, coming from a Java/C# background it was hard to get over the ingrained behavior I thought "this" should have.

While these books are available on GitHub for free, I prefer the analog version. This series is a must read for any serious Frontend Engineer.

Delightful Book that takes a unique survey of the basics of the language.

Overall, the treatment of the topic is quite good. It is, however, all but inexcusable that the book lacks an index. The book would otherwise be a great resource for settling language lawyer questions. As it is, it is not very useful for that purpose. Additionally, the splitting of the author's treatment of JS over six books seems a money grab from O'Reilly (a publisher that I generally like a great deal). Perhaps a single volume would have been unwieldy, but the series could (and should) have been issued in at most three titles.
