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.

This concise yet in-depth guide takes you inside scope and closures, two core concepts you need to know to become a more efficient and effective JavaScript programmer. Armed with this knowledge, you can achieve true JavaScript mastery. Learn about scope, a set of rules to help JavaScript engines locate variables in your code Go deeper into nested scope, a series of containers for variables and functions Explore function- and block-based scope,? It is a language which is also characterized as dynamic, weakly typed, prototype-based and multi-paradigm.

You Don't Know JS: ES6 & Beyond - Kyle Simpson Download

See this tweet from February 1st proving its realness:. It's a real book! The title of the entire Javascript series resonates with me. In my career, I deal with this insecurity about Javascript. Truly knowing Javascript is a touchy subject for many of us. Other Books on Code articles about Javascript and front-end development:. The book works to prep you thoroughly on how Javascript really thinks. The author, Kyle Simpson, imbues his writing with the principles in the famous programming book The Pragmatic Programmer : the book empowers all beginning software engineers with the root concepts so that they can think for themselves.

This is the opposite of the cowboy approach to learning Javascript programming. As a front-end web developer, I am hungry for this knowledge, and I am grateful for the information this book provides.

A great quote highlighting this idea comes from Chapter 2 :. It's very common to suggest that var should be avoided in favor of let or const! I believe this to be overly restrictive advice and ultimately unhelpful. It's assuming you are unable to learn and use a feature properly in combination with other features.

I believe you can and should learn any features available, and use them where appropriate! These principles puts me in a place of trusting the book and the wisdom it has to impart.

Everything is about why and how elements exist, which is why I am here. One of the greatest concepts all Javascript developers need to wrap their minds around is the this keyword.

Unlike other programming languages, this is dynamic. Get Started takes time with this, since getting clarity around it is a challenge. Get Started takes the time to explain not just how this behaves, but why :. Indeed, one of the main reasons this supports dynamic context based on how the function is called is so that method calls on objects which delegate through the prototype chain still maintain the expected this.

Get Started takes the time talking about what objects are in Javascript so that I can fully understand. It even acknowledges some strangeness up front. Get Started also shares that null returns object with the typeof operator, which is a Javascript bug to be cautious of.

The book also warns about equality mistakes that Javascript makes. Each chapter gets started with a bit of a warning: slow down and take your time.

Here is one such example from Chapter 1: About this Book :. I emphasize the word journey because knowing JS is not a destination, it's a direction. No matter how much time you spend with the language, you will always be able to find something else to learn and understand a little better. So don't look at this book as something to rush through for a quick achievement. Instead, patience and persistence are best as you take these first few steps.

Which is iterated again in Chapter 2 :. Please don't expect this chapter to be a quick read. It's long and there's plenty of detail to chew on. Take your time. And again in Chapter 3 :. Don't run so quickly through this material that you get lost in the weeds. As I've said a dozen times already, take your time. Even still, you'll probably finish this chapter with remaining questions.

That's OK, because there's a whole book series ahead of you to keep exploring! With Get Started , you do need to slow down to get the maximum benefit from the book. This can be true of many books. But for those who have taken my Get the Most From Technical Books free email course, you know that I am also about speed and extracting the most value from the time you invest. This does not mean extracting everything from the book that it has to offer.

The passages above give me mixed feelings, but I will start with the good:. Some great tactics to slow down and get the most from the material is by self-quizzing and taking notes by hand in fact, I made flash cards for Chapter 2 on Cram. Making yourself use and manipulate the information solidifies the connections in your mind. Many great technical books on programming also tell you to slow down. When the book poses a question, answer the question. Get out a pencil.

My previous review of Grokking Algorithms similarly encourages taking your time by answering the questions it asks throughout the book.

It also provides many natural breakpoints through white space and illustrations, so that slowing down is natural. Ways the book can do this is by asking questions and providing bullet-pointed summaries and natural breakpoints.

The book is dense in content and written mostly in paragraphs. Reading Get Started requires that you put forward more work to understand the material, but Get Started is so dense with wisdom, that is so hard-won and valuable, that the tradeoff can be worth it. But before moving on to the next section, a little story:. I was recently at a week-long immersive training to use a complex piece of software. The instructors were fun and kind; they put a lot of love into the curriculum they produced for us, but there was a problem:.

The structure is everything. Hierarchy is important when thinking about documentation. This review snapshot covers all the basics you need to understand about this book: the audience that suits this book best, its affordability, how much value the book brings, and most importantly, how fun the book is to read.

Since after all, books on programming ought to be fun to read. Their impression was that Javascript was not programming. That entered my consciousness early on. The material is also dense and goes by quickly. This book packs a lot of value, but it definitely does take slowing down with the text and doing homework to get the most from the material.

I recommend making flashcards based on what you learned and quizzing yourself. I had fun reading this book for the main reason that I got insights I found incredibly valuable and insightful. I felt like I was truly being enriched and made into a better Javascript developer, which is one of the best feelings out there.

Read this book if you want to iron out your kinks with using Javascript. Also keep in mind that this book is the introduction to a larger series of Javascript books. My suggestion for most readers is to proceed through this series in this order:.

Since the books in the series are granularly broken out, the series enables focus and prevents overwhelm to know that we can chunk and isolate areas where we can gain expertise.

JavaScript is a lightweight, interpreted, object-oriented language with first-class functions, most known as the scripting language for Web pages, but used in many non-browser environments as well such as Node. It is a prototype-based, multi-paradigm scripting language that is dynamic, and supports object-oriented, imperative, and functional programming styles. Scripting and automation tasks often need to extract particular portions of text from input data or modify them from one format to another. This book will help you learn JavaScript Regular Expressions, a mini-programming language for all sorts of text processing needs. Get Started, the first book in the new edition series, is where to start your journey of knowing JS more deeply. This book surveys the language in multiple layers of detail, laying out a roadmap with the other books as guides for your learning and growth. For any developer hoping to move from early JS experience to a deeper level, here is your first step to get started.
