    # When you use SIDE_MODULE you are opting int emscripten's dynamic linking system, 
    # which means you need to build a MAIN_MODULE and use the emscripten-generated js file 
    # for the that main module to then load the side module.
    # If you just want to build a standalone wasm module and don't want use emscripten generated JS then the option you probably want is -sSTANDALONE_WASM (However in this you don't even need that since it is the default setting when build to and output file with the .wasm extension). See https://v8.dev/blog/emscripten-standalone-wasm for more
