Summary:

Explore and master modern JavaScript techniques in order to build large-scale web applications About This Book Write powerful code with the high-level functions that JavaScript offers Test and debug issues with JavaScript code using various modern mechanisms Offers an expert's eye on the latest ES6 features and how these advanced tasks fit together in JavaScript as a whole Who This Book Is For This book is ideal for web developers who are looking to master modern JavaScript concepts and design principles. You should already have an intermediate level of JavaScript knowledge before starting this book. What You Will Learn Get a run through of the basic JavaScript language constructs Get familiar with the Functions and Closures of JavaScript Explore Regular Expressions in JavaScript Code using the powerful object-oriented feature in JavaScript Test and debug your code using JavaScript strategies Master DOM manipulation, cross-browser strategies, and ES6 Understand the basic concurrency constructs in Javascript and best performance strategies Learn to build scalable server application in JavaScript using Node.js In Detail JavaScript is a high-level, dynamic, untyped, lightweight, and interpreted programming language. Along with HTML and CSS, it is one of the three essential technologies of World Wide Web content production, and is an open source and cross-platform technology. The majority of websites employ JavaScript, and it is well supported by all modern web browsers without plugins. However, the JavaScript landscape has changed dramatically in recent years, and you need to adapt to the new world of JavaScript that people now expect. Mastering modern JavaScript techniques and the toolchain are essential to develop web-scale applications. Mastering JavaScript will be your companion as you master JavaScript and build innovative web applications. To begin with, you will get familiarized with the language constructs and how to make code easy to organize. You will gain a concrete understanding of variable scoping, loops, and best practices on using types and data structures, as well as the coding style and recommended code organization patterns in JavaScript. The book will also teach you how to use arrays and objects as data structures. You will graduate from intermediate-level skills to advanced techniques as you come to understand crucial language concepts and design principles. You will learn about modern libraries and tools so you can write bett...
