If you read this book cover-to-cover (well, except for the hefty reference pages), you will be a JavaScript expert.
I read a previous edition of this book cover-to-cover a few years ago and came out knowing almost nothing about Javascript. The problem was that I went in knowing absolutely nothing about Javascript.
The Rhino book is a reference, not a guide/tutorial. It's not there to guide you through writing your first Javascript script. Learn the basics of the language from another source, then read the Rhino book to get a more complete understanding. Otherwise you'll just be wasting your time.
