Applying the paradigms of core.async in ClojureScript
summary
Shows core.async running in ClojureScript with concrete code: a hello‑world that streams characters over a channel using timeouts-as-channels, a 10,000 go blocks grid demo that produces independent pulsing cells, and a render pipeline that uses the alts macro to read multiple channels and avoid channel overflow. Ports an Ants simulation to the browser, then profiles and speeds it up by replacing persistent vectors/maps with arrays and for‑loops; the optimized version runs much larger and noticeably faster.
