Secrets of the Javascript Ninja takes you on a journey towards mastering modern JavaScript development in three phases: design, construction, and maintenance. Written for JavaScript developers with intermediate-level skills, this book will give you the knowledge you need to create a cross-browser JavaScript library from the ground up.

About this Book

You can't always attack software head-on. Sometimes you come at it sideways or sneak up from behind. You need to master an arsenal of tools and know every stealthy trick. You have to be a ninja.

Secrets of the JavaScript Ninja leads you down the pathway to JavaScript enlightenment. This unique book starts with key concepts, like the relationships between functions, objects, and closures, taught from the master's perspective. You'll grow from apprentice to ninja as you soak up fresh insights on the techniques you use every day and discover features and capabilities you never knew about. When you reach the final chapters, you'll be ready to code brilliant JavaScript applications and maybe even write your own libraries and frameworks.

You don't have to be a ninja to read this book—just be willing to become one. Are you ready?
