I wrote a small "game" to showcase concurrent agents (via a library) working in a React app.<p>It demonstrates how a React program can be written with DOD-inspired pattern to make it easy to reason about, straightforward in re-render instruction semantic. Thus as the side effect the program is performant.<p>You're invited to view the source to examine the neat design pattern underneath as well as the agent management library that powers the app.<p>Caveat: it doesn't work well in mobile yet, so switch to desktop site mode.
