JavaScript: The Good Parts

Renting vs. Buying This Textbook

Renting is usually cheapest if you only need the book for one term: you return it with a free prepaid label when the term ends.

Rentals and used copies rarely include working access codes.

Always match the ISBN on your syllabus (9780596517748) before you order; different editions have different ISBNs.
