Bought as a gift for 12 year old Minecraft obsessed son in an attempt to get him to do something more proactive and useful with his (now) limited computer time. He absolutely loves the book, is learning coding, and Minecraft is thankfully fading inot the background!
Just check the syntax through carefully as a capital letter makes a difference and young ones aren't expert typists. Rapidly achieve results and my son was hooked straight away. Most amusing when he announced he was going to make an avatar with big balls.
