The purpose of the book is to give JavaScript developers a thorough understanding of JavaScript fundamentals, and how they can be used to solve real-world problems. A large focus of the book is on problems that have been encountered and solved while writing the major JavaScript libraries, particularly jQuery.
The book does not teach you how to use jQuery itself (that's the job of my other book:
jQuery in Action). it does aim to teach you how to write advanced JavaScript in a functional manner to best take best advantage of libraries such as jQuery.
