I am proud to present my solo hobby project NAND. This year-long undertaking follows the completed Nand to Tetris course, but ported to the web with its own runtime, user interface, and IDE. Using the "Load example program" selector, you can try out some programs I wrote on NAND's emulated hardware such as 2048, a genetic algorithm, and a manual stack overflow to corrupt the screen.Check out NAND at https://nand.arhan.sh
Additionally, I've authored an extensive writeup about the project. Read about it on the GitHub repository's readme.
