You dont know js code#
Instead of learning just enough to be dangerous, if you work through this series (preferably open in your browser of choice while writing and running all the code examples in your Developer Tools console), you should emerge with an understanding of closures, coercion, scope, hoisting, and the this identifier. I cannot recommend this series highly enough for anyone interested in JS. As a first book on JavaScript, it is everything that I thought it could be: concise, tightly written, absolutely disciplined, and devoid of the dead-tree filler found in much thicker programming books. This is where the You Don't Know JS series by Kyle Simpson rides in, Zorro-like, to save the day. Worse, if you're a current front or backend web developer coming to grips with JavaScript you are likely to be misled by hundreds of out-of-date online tutorials purporting to teach you "The Good Parts" of the language to the detriment of an in-depth understanding of the ecosystem, performant code, mechanics of lambdas, closures, prototypes, and other higher order functions. The irony is that JavaScript (as of 2018) is still a vastly misunderstood programming language regarded in many quarters as a toy or kludge limited to handling DOM manipulations and browser events.

Get an overview of other books in the series-and learn why it’s important to understand all parts of JavaScript Learn the essential programming building blocks, including operators, types, variables, conditionals, loops, and functionsīecome familiar with JavaScript's core mechanisms such as values, function closures, this, and prototypes 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. The series’ first book, Up & Going, provides the necessary background for those of you with limited programming experience. 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. 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.
