A quick introduction to my series on programming in NetsBlox (https://netsblox.org/). NetsBlox is a block-based programming language that stands on the shoulders of great projects like Scratch (https://scratch.mit.edu/) and Snap! (https://snap.berkeley.edu/). This series is also inspired by the Beauty and Joy of Computing curriculum (https://bjc.berkeley.edu/) and a course that I taught at Vanderbilt University (https://github.com/CliffordAnderson/CS1000). Welcome!
