This is an exciting time to learn JavaScript. Now that the latest JavaScript specification—ECMAScript 6.0 (ES6)—has been finalized, learning how to develop high-quality applications with this language is easier and more satisfying than ever. This practical book takes programmers (amateurs and pros alike) on a no-nonsense tour of ES6, along with some related tools and techniques.
 

Author Ethan Brown (Web Development with Node and Express) not only guides you through simple and straightforward topics (variables, control flow, arrays), but also covers complex concepts such as functional and asynchronous programming. You’ll learn how to create powerful and responsive web applications on the client, or with Node.js on the server.

• 
  •  Use ES6 today and transcompile code to portable ES5
• •  Translate data into a format that JavaScript can use
• •  Understand the basic usage and mechanics of JavaScript functions
• •  Explore objects and object-oriented programming
• •  Tackle new concepts such as iterators, generators, and proxies
• •  Grasp the complexities of asynchronous programming
• •  Work with the Document Object Model for browser-based apps
• •  Learn Node.js fundamentals for developing server-side applications
  
  Who This Book Is For

This book is primarily for readers who already have some experience with programming (even an introductory programming class, or an online course). If you’re new to programming, this book will be helpful, but you might want to supplement it with an introductory text or class. Those who already have some JavaScript experience (especially if it’s only in ES5) will find a practical and thorough coverage of important language concepts. Programmers who are coming from another language should feel right at home with the content in this book.
 

This book does attempt to comprehensively cover the language features, related tools, techniques, and paradigms that drive modern JavaScript development. Therefore, the material in this book necessarily ranges from the simple and straightforward (variables, control flow, functions) to the complicated and esoteric (asynchronous programming, regular expressions). Depending on your level of experience, you may find some chapters more challenging than others: the beginning programmer will no doubt need to revisit some of the material more than once.
