Mastering Modular JavaScript

If you have a working knowledge of JavaScript and ECMAScript 6 (ES6), this practical guide will help you tackle modular programming to produce code that's readable, maintainable, and scalable. You'll learn the fundamentals of modular architecture with JavaScript and the benefits of writing self-contained code at every system level, including the client and server.
Nicol�s Bevacqua, author of Practical Modern JavaScript, demonstrates how to scale out JavaScript applications by breaking codebases into smaller modules. By following the design practices in this book, senior developers, technical leaders, and software architects will learn how to create modules that are simple and flexible while keeping internal complexity in check.
