Same source as the desktop build, <code>GOOS=js GOARCH=wasm</code>, no fork, no duplicated file holding a &ldquo;web&rdquo; version of the solver.</p> <figure class="media-frame media-center fade-in media-gif"> <a href="https://crgimenes.itch.io/kutta"><img alt="Kutta shedding vortices at 20 degrees angle of attack" src="https://crg.eti.br/pt-br/post/kutta-no-navegador/vortices.webp" height="560" width="800" loading="lazy" decoding="async"></a> </figure> <p>Speed is what you pay. A solver step costs <strong>6.1 ms under wasm against 2.3 ms native</strong>, measured on the 360x200 grid the app runs, on an M4 Mac, same solver compiled for both targets on the same machine. Factor of 2.6.</p>
