Using the previous JS example (with some polishing), we start the conversion by copying the JS code into a C file. Step-by-step we run through the principles of converting this JS code into valid C code that we can compile into Web Assembly, based on the same principles we learnt in the initial lessons. We paste the C code into WASM Fiddle to get the resulting WebAssembly binary, and wire it into the application.

Note the demo is currently only supported in Chrome Canary with the Experimental Web Platform flag (chrome://flags/#enable-experimental-web-platform-feature) enabled due to the use of ES modules and WebGL 2.0.
