    A First Comparison of the Performance between JS and WebAssembly

    To compare the performance between JS and WebAssembly, we use an example that calculates the collisions between circles on the screen. This quickly slows down the rendering performance making the performance comparison visible. We briefly go over the same steps of converting JS into C code, and find that the JS version of the code is actually faster than the WASM version - WebAssembly improving performance is not such a simple argument.

    Demo repo: https://github.com/guybedford/wasm-demo

    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.
