About the Book

Wondering why JavaScript’s “this” is pointing to that, when you thought it was pointing over there? Confused by the seemingly arbitrary value of “this” … if it even has a value?

You’re not alone.

JavaScript’s context variable is one of the most frustrating and confusing bits of important information that you need to understand. But don’t worry – the rules for managing “this” are easier to understand than most people think. It only takes a little knowledge, a few examples to work with, and a willingness to travel the path. 

The name says it all: 5 Rules For Mastering JavaScript’s “this”. This book is split up in to multiple "days" - a short chapter each day, designed to guide you down the path of mastering "this". Every day, for 5 days, read the next chapter.  

Start The Journey

You’ll start with “Day 0″ an introduction that shows you the map that you’ll be following. From there, Day 1 starts you out on what may be the most difficult leg of the journey. If you can get past Day 1, the rest of the journey will be smooth sailing!

Along the way, you’ll learn lessons through examples and demonstrations of code that illustrate the rules and patterns for managing “this”. But beware – this isn’t a course that will give you all of the answers and demonstrations in a JSBin or JSFiddle. While you will see plenty of code samples, I have purposely left it up to you to run the code so that you can see what happens, first-hand. Work through the examples, study the text and put your knowledge to work in your applications. Taking a hands-on approach to learning "this" will equip you with the skills you need.
