A common thread running throughout most of my computer-book–writing 

career is that I tend to write a book I wish I had had in order to learn a new 

technology in the first place. Because I must write that book without the benefit of 

existing models, I begin by doing my best to master the technology, and then I write 

the book to help other newcomers learn as much as I did, but more quickly and 

with less pain, anguish, and confusion. To accomplish that goal, I write as much 

content as I feel is necessary to cover the topic in the depth that my readers 

require. 

When I started on what became the 4th and Gold editions of the Javaｓｃｒｉｐｔ Bible, 

there were models to follow (my previous three editions) plus a substantial amount 

of brand new material, much of which had not yet been documented anywhere. I 

also assumed the responsibility of integrating the frequently conflicting and competing 

philosophies of the ways the Javaｓｃｒｉｐｔ language is applied to a variety of 

browser brands and versions. Resolving these conflicts is a challenge that I face in 

my own programming work with clients, and I take great pleasure in sharing my 

solutions and approaches with other programmers floating in the same boat. 

As my editor and I began counting the pages I had assembled for these new editions, 

we discovered that the number of pages far outstripped the printer’s binding 

capabilities, even in a thicker volume made possible by using a hard cover (the 

Gold edition). Certainly not all of the words that I had written were so precious that 

some of them couldn’t be cut. But we were hundreds of pages beyond capacity. To 

cut that much content would have forced exclusion of coverage of language or document 

object model vocabulary. 

Fortunately, as had been done in previous editions, the plan for the new editions 

included Adobe Acrobat versions of the books on the accompanying CD-ROM. 

Although a significant compromise to ease of reading, it was possible to move some 

of the book’s content to the CD-ROM and leave the most important parts on the 

printed page. For the softcover 4th edition, reference chapters covering less-used or 

advanced subjects were pulled from print; for the hardcover Gold edition, which 

was longer and targeted more for professional ｓｃｒｉｐｔers, the advanced chapters 

were put back into the book (along with 15 additional chapters for that edition), 

and the Javaｓｃｒｉｐｔ tutorial was exiled to the CD-ROM.
