Expert JavaScript is your definitive guide to understanding how and why JavaScript behaves the way it does. Master the inner workings of JavaScript by learning in detail how modern applications are made. In covering lesser-understood aspects of this powerful language and truly understanding how it works, your JavaScript code and programming skills will improve. You will learn about core fundamentals of JavaScript, including deep dives into functions, scopes, closures, and practical object-oriented code. Mark Daggett explains clearly how closures, events, and asynchronous code really operate, as well as conventions and concepts to write JavaScript in a clear, pragmatic style. Many of the changes in ECMAScript6 and its implications are all explained. You'll be introduced to modern workflow tools to make application development faster, more enjoyable, and ostensibly more profitable. You'll understand how to measure code quality and write more testable JavaScript, and finally you'll learn about real-world applications of JavaScript, including JavaScript-powered robots. JavaScript is one of the most powerful languages on the web today, and it is only getting stronger. This book will take you through the process of planning, coding, testing, profiling and finally releasing your application, at expert level. With more frameworks and more improvements than ever, now is the time to become an expert at JavaScript. Make this journey - use Expert JavaScript today.
Putting it simply this is a awesome book. This is not a beginner book. This book has as main audience the professional developers who are seasoned in javascript that want to learn a litle more about the core features of the language and to become a little more broader on the applications and on the ecosystem of the language. Well in this respect this book takes a 10/10. The author starts with the first chapters by analysing the core concepts of the language, unlike some many other books the author didn't stop there. This book put javascript in a very broad perspective and show s the use of the virtual machine in other areas than the browser. The author does a good job introducing you into hardware programming with arduino and javascript for example. Things like testing and code quality are also taken seriously and a very large kit of technologies are explained how to use an exploit to make your code a professional one. Things like code metrics, testing and much more are taken in a very professional and pragmatical way. In a nutshell a very, very good book.
A complementary book for every JavaScript developer, specially for professional developers. Everyone who want to complete his/her knowledge about JavaScript must read this book.
