Preface

JavaScript has emerged as one of the most robust and versatile programming language around. Modern JavaScript embraces a vast array of time-tested and cutting edge features. Several of these features are slowly giving shape to the next generation of web and server platforms. ES6 introduces very important language constructs, such as promises, classes, arrow functions, and several, much anticipated features. This book takes a detailed look at the language constructs and their practical uses. This book doesn't assume any prior knowledge of JavaScript and works from the ground up to give you a thorough understanding of the language. People who know the language will still find it useful and informative. For people who already know JavaScript and are familiar with ES5 syntax, this book will be a very useful primer for ES6 features.
