The technology behind Figma is quite fascinating. From Twitter (<a href="https:&#x2F;&#x2F;twitter.com&#x2F;skuwamoto&#x2F;status&#x2F;672486788192055296" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;skuwamoto&#x2F;status&#x2F;672486788192055296</a>):<p>&gt; We’re using C++ → asm.js for most of our app, so it would be tough. React-canvas, seems incredible, tho.<p>&gt; The C++ → asm.js is via Emscripten. Everything else is done by our mad genius @evanwallace<p>Graphics engine is based on WebGL. Evan Wallace has done some incredible work. Using C++ is a smart move, an emergency exit to a native app. Yet I think a standalone app should be the priority.
