Learning JavaScript: JavaScript Essentials for Modern Application Development 3th edition PDF free download – Even though this is my second book on technologies in the JavaScript ecosystem, I still find myself somewhat surprised at my role as a JavaScript expert and evangelist. Like so many programmers, I held a strong prejudice against JavaScript up until about 2012. To do such an about-face still feels a little disorienting. My prejudice was for the usual reasons: I considered JavaScript a “toy” language (without really learning it properly, and therefore not knowing of what I spoke) that was practiced by dangerous, sloppy, untrained amateur programmers. There is a little truth in both of these reasons. ES6 was developed quickly, and even its inventor Bren‐ dan Eich admits there are things that he didn’t get right the first time around—and by the time he realized it, too many people were relying on the problematic behavior for him to effectively change it (show me the language that doesn’t suffer from this prob‐ lem, however). As for the second reason, JavaScript did make programming suddenly accessible. Not only did everyone have a browser, but with only a little effort, they could see the JavaScript that enabled the websites that were rapidly proliferating on the Web. People learned by trial and error, by reading each other’s code and—in so many cases—emulating poorly written code with insufficient understanding.

This book is primarily for readers who already have some experience with program‐ ming (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 (vari‐ ables, control flow, functions) to the complicated and esoteric (asynchronous pro‐ gramming, 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.
