Mastering Modular JavaScript

book

_{Now on Amazon!}

Tackle two aspects of JavaScript development: modularity and ES6. With this practical guide, front-end and back-end Node.js developers alike will learn how to scale out JavaScript applications by breaking codebases into smaller modules.

We’ll specifically cover features in ES6 from the vantage point of how we can leverage them to improve modularity in our programs. Learn how to manage complexity, how to drive it down, and how to write simpler code by building small modules.
