You don't need any prior experience with programming in order to gain value from this book. Considering a career change: Perhaps you are a K-12, junior college, or university student who has perhaps a bit of past programming experience, and you are pondering a full-time career as a software developer. Learning Scratch serves as an excellent diagnostic to gauge your aptitude and interest in the subject matter.Just tinkering: Maybe you are a technology buff who always wondered what work went into developing a software project. You have no real career aspirations in programming--you just enjoy tinkering and having fun. If you find that you don't belong in any of the previous three classifications, then don't worry about it. Set your sights on learning as much as you can and, above all else, having fun, and you'll be fine!
