Beginning javascript, 4th edition

Just put out $30 for _Beginning Javascript_ 4th edition, having started a JavaScript review and realized my first edition of said book was a "bit" dated. It is frustrating to find, already on p. 7, evidence of sloppy editing after the cut-and-paste of the update. Under the heading "Where do my scripts go?", instead of a general statement introducing the tag there's a paragraph that belongs (and actually appears) on p 9. The next paragraph ("Linking to an external JavaScript File") proceeds as if the tag has been introduced, as it starts: "The tag has another arrow in its quiver." But we haven't even been introduced to the tag, let alone learned about the "first" arrow in its quiver! If I weren't counting on having this updated book for reference, I would be tempted at this point to send it back for a refund. I hope this start isn't indicative of the quality of the book as a whole. Computers and word processors and desktop publishers can't substitute for careful copy editing. Come on, Wrox!
