Confident jQuery is for those who feel comfortable writing jQuery but want to improve their ability to structure their JavaScript better. If you have ever found yourself with messy JavaScript that is heavily tied to the structure of your HTML, or had your entire jQuery carousel refuse to start-up because you changed just one tiny class name in your HTML code, this book will help.

Through the course of this book we'll study and discuss:

how to make your code more structured and maintainable so you don't revisit it 6 months down the line and shudder.
how you can write cleverer, more contextual selectors to avoid your jQuery being quite so tightly tied to the HTML structure.
why not all your code should live within that one $(document).ready() call
how we can leverage plain JavaScript objects to clean our code up considerably
discuss refactoring methods to tackle old code and improve it
how in certain situations at all using jQuery is actually harder than using plain JavaScript
how to write tests for your jQuery
and much more.

What the book isn't

This book will not look at any additional libraries. We'll just be using jQuery all the way through (with the exception of QUnit for the testing chapter). This is not a book about telling you how to use RequireJS to load in your code in a modular fashion and nor will it tell you that you should use an additional library like Backbone or Angular.

This book is also not aimed at those who have never written jQuery before. You should have a good grasp of jQuery before tackling this book.

Questions?

I'd be happy to answer them. Please feel free to tweet @Jack_Franklin or email jack@jackfranklin.net.
