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

The truth is, we don’t know JavaScript

Reviewed in the United States on December 3, 2019

Verified Purchase

Kyle takes the perceived notions of JavaScript and makes you throw out that which you have perceived incorrectly. He shifts the our thought landscape of JavaScript being a squirrelly toy to being a powerhouse that is often used as well as misunderstood. Kyle is a thoughtful author that goes deep where needed and stays out of the compiler theorist type explanations where it would not be fruitful otherwise. While he doesn’t hide his opinion on a given topic, it’s not based in “feelings”, but that which is factually accurate. Buy every damn book in the series, you’ll be a better Engineer because if it. Bravo!!

The first JavaScript book you want to start

Reviewed in the United States on July 23, 2016

Verified Purchase

Definitely the book you want to start to learn JavaScript with. I knew a little bit about programming before I started this book but even if I didnt it covers all the basics. Kyle's style is very simple and he breaks everything down giving you a great explanation as to what is going on in the code. I will continue to checkout his other books as well. My recommendation is to use this book and sign up for FrontEndMasters. He teaches a course there intro to js which is pretty much this book but more in depth. I would recommend this book for anyone new to programming or trying to learn JavaScript.

Great Intro Book to Javascript

Reviewed in the United States on September 26, 2015

Verified Purchase

Definitely a beginner or intro book. I read through the whole thing in a little over an hour, a testament of being easy to follow but also being extremely short. One thing I didn't like (as others have mentioned) was the continual shout-outs to the other books in the series. If the author's goal was to whet the taste buds of the reader and tempt them into buying the rest of the series, he's certainly committed. Granted, even from the title of this book it is clear it was made to be entry-level reading material. The author did make me chuckle in the Preface with a clear call-out to another well known JavaScript book implying that even the title was degrading to the power and perception of the language.

For beginners or people new to JavaScript, I would recommend it. It covers all the necessities to get someone "Up & Going" for lack of better words. For those with knowledge in other languages, the author does highlight a couple key aspects of JavaScript such as closures that might help lay the basis for further reading. If you have any measurable experience with the language, most of this book will just be a review.

Overall, I bought this book for $4.99. For less than the cost of a fast food meal, there's plenty of knowledge written in an inviting manner that should be easy for a beginner to follow along and learn with.

Highly recommend if you want to get serious about Javascript

Reviewed in the United States on August 16, 2015

This is a great book for anyone that wants to start getting serious about javascript. If you're just going to copy and paste a couple jquery plugins, this might not be for you, but if you want to be a true Javascript artist, this is the entry point. This is the first book in the "You don't know Javascript" series. I would recommend not skipping this intro into the series, it lays the framework for your entire future as a Javascript artist. From variables to closures. Even if you have some experience, this edition will probably teach you a thing or two and get you ready to deep dive into serious scripting.

Excellent author - instructive pace and detail

Reviewed in the United States on March 7, 2016

Verified Purchase

What I have read so far is excellent instruction. This opinion from an engineer with limited but reasonable code background, enough to follow good technical information that is meant to teach a technical subject for true understanding. True understand? Many books in technical subjects are written to virtually insure only the best can stay with it or require a class (textbook) to move through the material (and get class time for questions). We called it weeding it out, in college. This series is not that, but written like the rare technical teacher who really wants people to stay interested and learn.

A great introduction to JS and basic programming constructs

Reviewed in the United States on January 12, 2016

Verified Purchase

Was recommended this book series before but decided to go the route of Eloquent JavaScript. While EJ is a great book, filled with humor and detailed explanations, reading it was pretty challenging as someone who is new to programming.

Enter YDKJS

The book is laid out succinctly and, maybe more importantly, for the layman. It assumes no prior knowledge, which was EJ'S sold weakness. The author's passion for the language and ALL of its features seems to burst from every word in this very terse book. I wish I would have started this series sooner, to be honest.

Good to learn the very basics

Reviewed in the United States on April 14, 2020

Not substantial on its own to learn JavaScript. Supplemental books will be required to get a better knowledge base of JS. But I like the way Kyle Simpson explains the concepts and has a quirky sense of humor. It's good for beginners. However YouTube videos are free so I'd recommend using those first.

Giving Up & Going a "B/B+" Geek Grade

Reviewed in the United States on September 16, 2017

Verified Purchase

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.

Excellent, to the point introduction for those new to Javascript

Reviewed in the United Kingdom on January 7, 2019

Verified Purchase

This book is an excellent introduction for those who haven't used Javascript before. Although I find it to be a bit too short, and it skips a lot. It is only here to give you an overview of what's possible. Users with some experience in Javascript can probably skip this title and read all the others in the series.
The book series "You Don't Know JS" itself goes very in-depth in some areas and is rather targeted towards experienced programmers, but this book is an introduction which covers most important features of the language, which are covered in more detail in subsequent books.
Even for people completely new to the language, I highly advise you to consult additional resources if you want to take learning this language seriously. Even for beginners, what's contained in this book alone is just not enough.
As the author also mentions, knowing only half of the language is only going to hurt you. You'll be misinformed, and write bugs, and as a result blame the "ugly" language and write "hacks" to bypass behavior. I call this unprofessional.
A programmer who loves his craft will actually learn what he's doing, and embrace it.

A deceptively valuable introduction

Reviewed in the United Kingdom on November 20, 2015

Verified Purchase

I am an experienced developer, coming from a 'classical' language background. I've always been able to keep my hand in with Javascript - bits and pieces... but never taken the time to learn it properly.
Enter Kyle Simpsons YDKJS series.
This, the first book of the series, is an introduction. Just because you're a seasoned developer doesn't mean you should skip it. It will confirm and clarify the very basics of the language (could you honestly explain to someone the reason and difference between == and === ?)
The book is only 67 odd pages, but jammed with a crucial foundation to get you "up and going"!
broken into the following sections:
1. Into Programming
2. Into Javascript
3. Into YDKJS
They serve as both a solid foundation and teaser to the rest of the series. Yes the books are available on Github opensource... however, this short form factor of the books makes them so accessible. Instead of lugging around war and peace you can cherry pick these books to through in your bag. I prefer to read these in printed form as opposed to electronic... because of their compact size and short page count.
This could be a good model for others to follow... shorter, cheaper chunks.
Despite being Open Source, I'm happy to pay the price of a (UK) coffee for this fantastic little resource. Get it bought.

A great introduction to JavaScript and the You Don't Know JS series.

Reviewed in the United Kingdom on January 23, 2016

Verified Purchase

This book is divided into three sections. Introductions to programming, JavaScript and the YDKJS series. It is short, easy to digest and written in an approachable style. If I were new to programming I would read this book then get some more programming experience before moving on to the rest in the series. If you are an experienced programmer then you can go straight into the rest of the series.

Which leads me to my only criticism, the price of the remaining books in the series. To learn all you need to know about the more esoteric but essential parts of the language then you should really read all the books in the series. But at £60 for all of them it's a bit much, especially when you can just go to youdontknowjs.com to read them all online. The price of the print books are holding back the series from becoming programming classics.

Manual iniciante pra quem quer conhecer bem a linguagem

Reviewed in Brazil on January 31, 2016

Verified Purchase

O mérito dos livros do Kyle Simpson é que ele expõem nuances e pontos importantes da linguagem JavaScript de forma fácil mas não simplória.

Este livro em particular é para aqueles que nunca tiveram contato com a linguagem ou que tiveram um contato superficial com a mesma e a desejam conhecer melhor. O que mais gostei nesse livro é que ele faz um "resumão" da linguagem JavaScript com tudo o que você precisa saber de importante para já começar a trabalhar. Mas ele deixa bem clara que em alguns tópicos como (this, closure, etc) é apenas um resumo e que ele dedica outros livro para esse tópico.

Essa abordagem tem o mérito de permitir o neófito do JavaScript a ser produtivo e lhe dar a chance de se tornar mais proficiente na linguagem. Além disso, para aqueles que "conhecem" a linguagem apresenta a lista de tópicos descrita em outros livros para que se possa aprofundar na linguagem. Ou seja, no final deste livro tem-se a lista de todos os livros da seria e a abordagem que ele toma em cada um desses livros bem como o porque ele necessitou escreve-los.

Recomendo
