Hi hi hi! Welcome to The Nature of Code book! You can read the whole thing right here, thank you Creative Commons! If this project sparks joy and want to support it, you can sponsor on GitHub or grab a copy of an artfully bound collection of processed cellulose fibers, imprinted with symbolic glyphs via pigment-based transfer particles, available at No Starch Press and other places where people buy books. Don't forget to touch grass!
