AI-assisted independent implementation experiment
Build useful npm capabilities from zero.
Published TypeScript utilities with runnable browser demos, source links, installation notes and dated package evidence.
Every independent implementation starts from zero, publishes its own source and provides a runnable browser demonstration. The collection currently covers 40 packages.
Independent implementation, not source recovery.
The experiment uses AI to accelerate implementation, testing and documentation. Abandoned source code is not reused; the current repository, runnable behavior and human maintainer are the evidence shown.
No abandoned source code is copiedNew behavior is demonstratedMissing historical mappings are disclosed
