Webassembly and javascript performance comparison

Requirements

• webpack
• npm
• emscripten

To compile

Run npm install.

To compile the C environment to Javascript run:

emcc src/js/modules/c/environment.c -o src/js/modules/c/environment.js

or for best performance:

emcc src/js/modules/c/environment.c -o src/js/modules/c/environment.js -s NO_EXIT_RUNTIME=1 -O3 -Oz --memory-init-file 0

then add export {Module as default} at the end of the file src/js/c/environment.js

then run webpack

To choose between C, Vanilla js and web workers

Modify the strategy constant passed to game function in app.js, you can choose between:

• vanilla for simple Vanilla JS.
• workers for the Vanilla JS strategy which uses web workers to split the calculation in multiple threads.
• wasm for the strategy which uses C compiled functions to calculate the next state.
