This complete lot includes JavaScript All-in-One (7 books in one), Machine Learning 2nd Edition, Networking All-in-One 8th edition (10 books in one), Artificial Intelligence 3rd edition, Cybersecurity 2nd edition, Hacking 7th edition, and Coding All-in-One 2nd edition (7 books in one), For Dummies. Every book is in excellent condition. Their covers show signa of wearing due to how they were stored, but the majority are unused and untouched. However, the Networking book does show a little more signs of use (some pages up to page 50 are slightly wrinkled, but not enough to be too noticeable. Everything past 50 is in pristine condition). Other than that, every other book has no highlighting, writing, tears, or folds.
