Product Description

It’s easy to learn parts of JavaScript, but much harder to learn it completely—or even sufficiently—whether you’re new to the language or have used it for years. With the "You Don’t Know JS" book series, you’ll get a more complete understanding of JavaScript, including trickier parts of the language that many experienced JavaScript programmers simply avoid.

The series’ first book, Up & Going, provides the necessary background for those of you with limited programming experience. By learning the basic building blocks of programming, as well as JavaScript’s core mechanisms, you’ll be prepared to dive into the other, more in-depth books in the series—and be well on your way toward true JavaScript.

With this book you will:

  • Learn the essential programming building blocks, including operators, types, variables, conditionals, loops, and functions
  • Become familiar with JavaScript's core mechanisms such as values, function closures, this, and prototypes
  • Get an overview of other books in the series—and learn why it’s important to understand all parts of JavaScript

4Giving Up & Going a "B/B+" Geek Grade
By Coffee-N-Donuts (AKA) ThisGeekChick
This book delivers exactly what it claims to contain. Any beginner or intermediate JavaScript developer can benefit from this book. What makes this so special is Kyle Simpson does a very good job at breaking down the most fundamental concepts such as scope, blocks and I/O as well as not stopping at defining, but takes things a step further by defining how basic JavaScript operates. Even more advanced developers can find use of this lean, but mean reference book. Examples are clean and concise.
At the cost, all front-end, back-end and full stack developers should have this sitting among their technical book collection. Cheaper than many e-books.
My only issue (and this may be the case for me alone) lies with the print quality. Beginning with the Foreword and ending with the Appendix section, I have counted fourteen (14) pages with variable print density: left of each page suggest low-toner or my book was at the end of print batch run. Nonetheless, words are fairly visible, but I had to remove one star for this issue alone.

Final verdict: Content is resourceful (grade A) which is all you can ask for in when it comes to technical reference material, however the print quality (C) needs quality check before shipping out to vendors.

5Great introduction to the JavaScript language
By Tiffany White
Great introduction to the JavaScript language, with bits of the new standard, ES6 or ES2015 included. Browser support for ES2015 is limited so I don't know how much use you're going to get out of those examples without a transpiler, but for what you get in this book, despite its thinness and the fact it is available online for free, it's totally worth the buy. This is one you need on your bookshelf for future reference.

4good price and clear expression of JS closures
By Andrew George
It's good. A bit long winded at times, but, as a book primarily focused on lexical scoping, it doesn't wander too much. The more I think about it, the more I would have opened with something like:
Closures, as pertains to JavaScript/JS/ECMAscript/ES, is a concept founded in lexical scoping. Lexical scoping is the scope introduced as part of the authoring process, or upon interpretation of an authored script. The authored script is simply the character stream entered by the coder or IDE.

Instead there's a story about JS engines or something. While I do feel that it is important to consider how a scripting system interprets and operates, that information is probably best set in an appendix with a quick touch on the topics and a referral to the back of the book (this could also improve consistency of the series.) Small, focused, information at the top with background at the back. Technical book mullet? IDK...
